Description

SUSPENSION UNIT FOR A HELMET

BACKGROUND

Technical Field

This disclosure generally relates to suspension units for hard hats and other helmet structures to enhance user safety and helmet functionality, and, more particularly, to suspension units having one or more sensors arranged to obtain biometric, environmental, location, motion, impact and/or other data from which to enhance user safety and helmet functionality.

Description of the Related Art

Helmets and other protectable wearables are often required when working in areas where there is a potential for injury. Helmets are especially required to protect the head from hazards such as impact from falling objects, scraping or hitting one's head on equipment, or contact with electrical conductors. Traditional helmet suspension units (also referred to as harnesses) have been designed to extend inside the helmet and be used for spreading the helmet's weight and the force of any impact over the top of a user's head.

At least one suspension unit or harness is known which includes biometric sensors for measuring biometric data of a wearer and an electrical interface for receiving power from a power source of a mating helmet structure and for transferring data collected by the suspension unit to a control unit of the mating helmet structure, as shown and described in US Patent No. 9,642,574. Notably, such a suspension unit and helmet structure combination suffers from various drawbacks, including that the suspension unit requires a specialized mating helmet structure to function and cannot be used with a variety of helmet shells on the market and currently in use in the workforce and elsewhere. BRIEF SUMMARY

Embodiments described herein provide a suspension unit that is removably coupleable to a suspension attachment scheme of a conventional helmet shell to enhance user safety and helmet functionality without disrupting or jeopardizing the integrity of the helmet structure or requiring modifications thereto. In this manner, the suspension unit may serve as a drop-in

replacement for conventional suspension units (also referred to as harnesses) of traditional hard hats and other helmet structures (e.g., climbing helmets, bike helmets).

According to one embodiment, a suspension unit removably coupleable to a suspension attachment scheme of a helmet shell to enhance user safety and helmet functionality may be summarized as including: a suspension assembly configured to support the helmet shell on a user’s head and including a head engagement structure and one or more coupling devices configured to interface with the suspension attachment scheme of the helmet shell to enable removable attachment of the suspension unit to the helmet shell; one or more sensors carried by the suspension assembly and arranged to obtain biometric, environmental, location, motion, impact and/or other data; and a control system carried by the suspension assembly, the control system including at least a power source and a communication module, and being operatively coupled to the one or more sensors to obtain the biometric, environmental, location, motion, impact and/or other data and to transmit, via the communication module, a data signal to a computing device or network based at least in part on said biometric, environmental, location, motion, impact and/or other data from which to enhance user safety and helmet functionality.

The control system carried by the suspension assembly may further include a processor for processing the biometric, environmental, location, motion and/or other data onboard the suspension unit, and may further include a memory for storing data onboard the suspension unit. In this manner, processing of the data may be completed onboard the suspension unit and optionally stored in memory onboard the suspension unit. The one or more sensors may include at least one of a biometric sensor, an environmental sensor, a location sensor, an orientation sensor, a motion sensor and an impact sensor. In this manner, the sensor(s) may be configured to obtain biometric data (e.g., body temperature, heart rate), environmental data (e.g., environmental temperature), user location data, user orientation data, user motion data and/or impact data for subsequent

processing from which to enhance user safety or helmet functionality.

The helmet shell may include a multi-point suspension attachment scheme, and the suspension assembly may include an arrangement of coupling devices that is configured to interface with said multi-point suspension attachment scheme. For example, the multi-point suspension attachment scheme of the helmet shell may be a conventional 4-point or conventional 6- point attachment scheme, and the arrangement of coupling devices of the suspension assembly may be configured to interface with the conventional 4- point or conventional 6-point attachment scheme of the helmet shell. In this manner, the suspension unit can attach directly to a wide variety of helmet shells already on the market and in use in the workforce and elsewhere.

In some instances, the head engagement structure of the suspension assembly may include a primary loop configured to at least partially surround a circumference of a user’s head and one or more suspension straps coupled to the primary loop to extend over the crown of the user’s head. In this manner, the head engagement structure may reflect or resemble a conventional suspension unit or harness.

In some instances, the suspension unit may further include a haptic device carried by the suspension assembly and communicatively coupled to the control system for delivering haptic feedback to a user. Such haptic feedback may be based at least in part on the data obtained by the suspension unit during use. For example, the suspension unit may obtain location data, orientation data and/or motion data from which it may be determined that a user is approaching a hazard or in the path of a hazard and based upon which the user may be provided with a haptic warning. In some instances, the suspension assembly may include a control system enclosure containing at least a portion of the control system, and the control system enclosure may in some instances be malleable, pliable, flexible and/or deformable.

The suspension assembly may further include a fit adjustment assembly for adjusting a fit of the head engagement structure (e.g., an adjustable band with ratchet device), and the fit adjustment assembly may include a housing containing at least a portion of the control system. The power source of the control system and/or the communication module may be contained, for example, in the housing of the fit adjustment assembly.

In some instances, the suspension unit may comprise a plurality of sensors and at least one of the sensors may be mounted in a first region of the head engagement structure and at least one of the sensors may be mounted in a second region of the head engagement structure that is distinct from the first region. Sensors may be positioned, for example, in one or more of the following regions: a brow region; a forehead region, a temple region; or a crown region.

The suspension unit may further include a speaker and/or a microphone carried by the suspension assembly and operatively coupled to the control system from which to enhance user safety or helmet functionality. For example, the speaker, when provided, may be used to provide audible instructions or warnings to the user based at least in part on data obtained by the suspension unit. As another example, the microphone, when provided, may be used by the user to provide voice commands or to provide user input to supplement or modify the data collected by the suspension unit.

The suspension unit may further include one or more user manipulable controls (e.g., switches, buttons) carried by the suspension assembly and operatively coupled to the control system from which to control or manipulate aspects of the suspension unit. For example, the suspension unit may include a power switch or button from which to activate and deactivate functionality of the suspension unit. In a particularly advantageous aspect, the suspension unit is provided as a self-contained unit that is readily attachable to the suspension attachment scheme of a conventional helmet shell and electrically functional apart from the helmet shell. In this manner, the suspension unit does not need to rely on the helmet shell for power or other aspects.

According to another embodiment, a system may be summarized as including: a helmet shell with a suspension attachment scheme; and a suspension unit removably attachable to the helmet shell via the suspension attachment scheme. The suspension unit includes: a suspension assembly having a head engagement structure and one or more coupling devices configured to interface with the suspension attachment scheme of the helmet shell to enable removable attachment of the suspension unit to the helmet shell; one or more sensors carried by the suspension assembly and arranged to obtain biometric, environmental, location, motion, impact and/or other data; and a control system carried by the suspension assembly, the control system including at least a power source and a communication module, and being operatively coupled to the one or more sensors to obtain the biometric, environmental, location, motion, impact and/or other data and to transmit, via the communication module, a data signal based at least in part on said biometric, environmental, location, motion, impact and/or other data to a computing device or network from which to enhance user safety and helmet functionality.

The system may further include a light-emitting unit removably attachable to an exterior of the helmet shell, which operates in parallel or tandem with the suspension unit. The light-emitting unit may include: one or more light sources; and a light-emitting unit control system, the light-emitting unit control system communicatively coupled, either directly or via the

computing device or network, to the control system of the suspension unit, and being configured to control the light sources to emit light based at least in part on the data signal transmitted by the communication module of the control system of the suspension unit. In this manner, the suspension unit may be used to collect various data and the light-emitting unit may be illuminated based at least in part on said data.

In some instances, the control system of the suspension unit may be communicatively coupled to the computing device or network via the light- emitting unit control system. In this manner, data may be obtained by the suspension unit, transmitted to the light-emitting unit and then transmitted to the computing device or network for further processing, storage or other action.

In some instances, the light-emitting unit may include one or more light-emitting unit sensors arranged to obtain environmental, location, motion, impact and/or other data to supplement the data obtained by the suspension unit. For example, the light-emitting unit may include a temperature and/or humidity sensor from which to obtain environmental data in the vicinity of the user, which environmental data may be used to supplement and/or modify other data (e.g., biometric data) obtained by the suspension unit.

The light-emitting unit and the suspension unit may be pairable with each other directly or via the computing device or network to facilitate a transfer of data from the suspension unit to the light-emitting unit and/or a transfer of data from the light-emitting unit to the suspension unit. In this manner, data may be shared between the distinct devices and the data obtained from each may be combined as desired.

The suspension unit may be a self-contained unit that is readily attachable to the suspension attachment scheme of a conventional helmet shell and electrically functional apart from the helmet shell. Similarly, the light- emitting unit may be a self-contained unit that is readily attachable to the exterior of a conventional helmet shell and electrically functional apart from the helmet shell. In this manner, the helmet shell may be a conventional helmet shell that lacks electronic functionality and both devices may be readily secured to the helmet shell without jeopardizing its integrity.

According to yet another embodiment, a system for use with a helmet shell having a suspension attachment scheme may be summarized as including: a suspension unit removably attachable to an interior of the helmet shell via the suspension attachment scheme; and a light-emitting unit removably attachable to an exterior of the helmet shell. Advantageously, the suspension unit includes: a suspension assembly configured to support the helmet shell on a user’s head and including a head engagement structure and one or more coupling devices configured to interface with the suspension attachment scheme of the helmet shell to enable removable attachment of the suspension unit to the helmet shell, one or more sensors carried by the suspension assembly and arranged to obtain biometric, environmental, location, motion, impact and/or other data, and a control system carried by the suspension assembly, the control system including at least a power source and a communication module, and being operatively coupled to the one or more sensors to obtain the biometric, environmental, location, motion, impact and/or other data and to transmit, via the communication module, a data signal based at least in part on said biometric, environmental, location, motion, impact and/or other data to a computing device or network from which to enhance user safety and helmet functionality. Advantageously, the light-emitting unit includes: one or more light sources, and a light-emitting unit control system, the light-emitting unit control system communicatively coupled, either directly or via the computing device or network, to the control system of the suspension unit, and being configured to control the light sources to emit light based at least in part on the data signal transmitted by the communication module of the control system of the suspension unit. In a particularly advantageous aspect, the suspension unit is provided as a self-contained unit that is readily attachable to the suspension attachment scheme of a conventional helmet shell and electrically functional apart from the helmet shell, and the light-emitting unit is similarly provided as a self-contained unit that is readily attachable to the exterior of a conventional helmet shell and electrically functional apart from the helmet shell.

As an example, Figure 1 is a perspective view of a conventional hard hat 10 that is typical of those worn by workers in the construction industry, including a helmet shell 12 (shown transparent) and a suspension unit 14 (also referred to as a harness). Advantageously, a user may simply remove the conventional suspension unit 14 shown in Figure 1 by disconnecting the suspension unit 14 from the conventional suspension attachment scheme 16 (a 4-point attachment scheme shown) provided in the helmet shell 12, and may replace it with embodiments of the suspension units disclosed herein to provide enhanced functionality.

Figure 2 shows one example embodiment of a suspension unit 20 that is removably coupleable to the suspension attachment scheme 16 of a conventional helmet shell 12 (Figure 1 ) to enhance user safety and helmet functionality. The suspension unit 20 includes a suspension assembly 22 having a head engagement structure 24 and one or more coupling devices 26 configured to interface with the suspension attachment scheme 16 of the conventional helmet shell 12 to enable removable attachment of the suspension unit 20 to the helmet shell 12. The head engagement structure 24 of the suspension assembly 22 may include, for example, a primary loop 28

configured to at least partially surround a circumference of a user’s head and one or more suspension straps 30 coupled to the primary loop 28 to extend over the crown of the user’s head. In this manner, the head engagement structure 24 may reflect or resemble a conventional suspension unit or harness. In addition, the coupling devices 26 may be configured to interface with a multi- point suspension attachment scheme 16 of the conventional helmet shell 12.

For example, the multi-point suspension attachment scheme of the helmet shell 12 may be a conventional 4-point attachment scheme (Figure 1 ) or

conventional 6-point attachment scheme, and the arrangement of coupling devices 26 of the suspension assembly 22 may be configured to interface with the conventional 4-point or conventional 6-point attachment scheme 16 of the helmet shell 12. As such, the suspension unit 20 can attach directly to a wide variety of helmet shells already on the market and in use in the workforce and elsewhere.

Advantageously, the suspension unit 20 further includes one or more sensors 40a-d (collectively 40) carried by the suspension assembly 22 and arranged to obtain biometric, environmental, location, motion, impact and/or other data.

temperature, heart rate), environmental data (e.g., environmental temperature), user location data, user orientation data, user motion data and/or impact data for subsequent processing from which to enhance user safety or helmet functionality. At least one of the sensors may be mounted in a first region of the head engagement structure 24 and at least one of the sensors may be mounted in a second region of the head engagement structure 24 that is distinct from the first region. Sensors may be positioned, for example, in one or more of the following regions: a brow region; a forehead region, a temple region; or a crown region.

The suspension unit 20 further includes a control system 50 carried by the suspension assembly 22, the control system 50 including at least a power source 52 and a communication module 54, and being operatively coupled to the one or more sensors 40a-d to obtain the biometric,

environmental, location, motion, impact and/or other data and to transmit, via the communication module 54, a data signal to a computing device (e.g., smartphone) or network based at least in part on said biometric, environmental, location, motion, impact and/or other data from which to enhance user safety and helmet functionality. The control system 50 carried by the suspension assembly 22 may further include a processor 56 for processing the biometric, environmental, location, motion and/or other data onboard the suspension unit 20, and may further include a memory 58 for storing data onboard the

suspension unit 20. In this manner, processing of the data may be completed onboard the suspension unit 20 and optionally stored in memory 58 onboard the suspension unit 20.

In some instances, the suspension unit 20 may further include a haptic device 60 carried by the suspension assembly 22 and communicatively coupled to the control system 50 for delivering haptic feedback to a user. Such haptic feedback may be based at least in part on the data obtained by the suspension unit 20 during use. For example, the suspension unit 20 may obtain location data, orientation data and/or motion data from which it may be determined that a user is approaching a hazard or in the path of a hazard and based upon which the user may be provided with a haptic warning.

The suspension assembly 22 may further include a fit adjustment assembly 32 for adjusting a fit of the head engagement structure (e.g., an adjustable band with ratchet device), and the fit adjustment assembly 32 may include a housing 34 containing at least a portion of the control system 50. The power source 52 of the control system 50 and/or the communication module 54 may be contained, for example, in the housing 34 of the fit adjustment assembly 32.

In some instances, the suspension assembly 22 may include a control system enclosure containing at least a portion of the control system 50, and the control system enclosure may in some instances be malleable, pliable, flexible and/or deformable.

The suspension unit 20 may further include a speaker 62 and/or a microphone 64 carried by the suspension assembly and operatively coupled to the control system 50 from which to enhance user safety or helmet functionality. For example, the speaker 62, when provided, may be used to provide audible instructions or warnings to the user based at least in part on data obtained by the suspension unit 20. As another example, the microphone 64 may be used by the user to provide voice commands or to provide user input to supplement or modify the data collected by the suspension unit 20.

The suspension unit 20 may further include one or more user manipulable controls 66 (e.g., switches, buttons) carried by the suspension assembly 22 and operatively coupled to the control system 50 from which to control or manipulate aspects of the suspension unit 20. For example, the suspension unit 20 may include a power switch or button from which to activate and deactivate functionality of the suspension unit 20.

In a particularly advantageous aspect, the suspension unit 20 is provided as a self-contained unit that is readily attachable to the suspension attachment scheme 16 of a conventional helmet shell 12 (Figure 1 ) and electrically functional apart from the helmet shell 12. In this manner, the suspension unit 20 does not need to rely on the helmet shell 12 for power or other aspects.

Figure 3 shows another example embodiment of a suspension unit 20' having similar features and functionality to the embodiment of the suspension unit 20 shown in Figure 2.

For example, the suspension unit 20' shown in Figure 3 includes a suspension assembly 22' having a head engagement structure 24' and one or more coupling devices 26' configured to interface with the suspension attachment scheme 16 of a conventional helmet shell 12 (Figure 1 ) to enable removable attachment of the suspension unit 20' to the helmet shell 12. The head engagement structure 24' of the suspension assembly 22' may include, for example, a primary loop 28' configured to at least partially surround and engage a circumference of a user’s head.

The suspension unit 20' further includes one or more sensors 40a' -d' (collectively 40') carried by the suspension assembly 22' and arranged to obtain biometric, environmental, location, motion, impact and/or other data. For example, and without limitation, the suspension unit 20' may include a biometric sensor 40a' configured to collect biometric data, an environmental sensor 40b' configured to collect environmental data, a location sensor 40c' configured to collect location data, and/or a motion sensor 40d' configured to collect motion data. Other sensors may include, without limitation, an orientation sensor and an impact sensor. In this manner, the sensor(s) 40' may be configured to obtain biometric data (e.g., body temperature, heart rate), environmental data (e.g., environmental temperature), user location data, user orientation data, user motion data and/or impact data for subsequent processing from which to enhance user safety or helmet functionality as described in more detail elsewhere. The sensors 40' may be positioned, for example, in one or more of the following regions: a brow region; a forehead region, a temple region; or a crown region. As shown in Figure 3, for example, the sensors 40' may be positioned across the forehead region of a user. One or more of the sensors 40' may be positioned beneath a forehead cushioning element 42' and, if required, exposed to the user or the surrounding

environment via an appropriate aperture. One or more of the sensors 40' may be positioned on or within the forehead cushioning element 42'. The forehead cushioning element 42' may be removably coupled to the primary loop 28' of the suspension assembly 22' to facilitate cleaning thereof and/or servicing or replacement of the sensors 40'.

The suspension unit 20' further includes a control system 50' carried by the suspension assembly 22', the control system 50' including at least a power source 52' and a communication module 54', and being operatively coupled to the one or more sensors 40' to obtain the biometric, environmental, location, motion, impact and/or other data and to transmit, via the communication module 54', a data signal to a computing device (e.g., smartphone) or network based at least in part on said biometric, environmental, location, motion, impact and/or other data from which to enhance user safety and helmet functionality. The control system 50' carried by the suspension assembly 22' may further include a processor 56' for processing the biometric, environmental, location, motion and/or other data onboard the suspension unit 20', and may further include a memory 58' for storing data onboard the suspension unit 20'. In this manner, processing of the data may be completed onboard the suspension unit 20' and optionally stored in memory 58' onboard the suspension unit 20'.

In some instances, the suspension unit 20' may further include a haptic device carried by the suspension assembly 22' and communicatively coupled to the control system 50' for delivering haptic feedback to a user. Such haptic feedback may be based at least in part on the data obtained by the suspension unit 20' during use. For example, the suspension unit 20' may obtain location data, orientation data and/or motion data from which it may be determined that a user is approaching a hazard or in the path of a hazard and based upon which the user may be provided with a haptic warning.

The suspension assembly 22' may further include a fit adjustment assembly 32' for adjusting a fit of the head engagement structure (e.g., an adjustable band with ratchet device), and the fit adjustment assembly 32' may include a housing 34' containing at least a portion of the control system 50'.

The power source 52' of the control system 50' and/or the communication module 54' may be contained, for example, in the housing 34' of the fit adjustment assembly 32'. In the example embodiment of Figure 3, the communication module 54' is provided in an area remote from the fit adjustment assembly 32'.

The suspension unit 20' may further include a speaker and/or a microphone carried by the suspension assembly 22' and operatively coupled to the control system 50' from which to enhance user safety or helmet

functionality. For example, the speaker, when provided, may be used to provide audible instructions or warnings to the user based at least in part on data obtained by the suspension unit 20'. As another example, the microphone may be used by the user to provide voice commands or to provide user input to supplement or modify the data collected by the suspension unit 20'.

The suspension unit 20' may further include one or more user manipulable controls (e.g., switches, buttons) carried by the suspension assembly 22' and operatively coupled to the control system 50' from which to control or manipulate aspects of the suspension unit 20'. For example, the suspension unit 20' may include a power switch or button from which to activate and deactivate functionality of the suspension unit 20'.

In a particularly advantageous aspect, the suspension unit 20' is provided as a self-contained unit that is readily attachable to the suspension attachment scheme 16 of a conventional helmet shell 12 (Figure 1 ) and electrically functional apart from the helmet shell 12. In this manner, the suspension unit 20 does not need to rely on the helmet shell 12 for power or other aspects.

Embodiments of the suspension units 20, 20' described herein may be used to collect a wide variety of data (e.g., biometric data,

environmental data, location data, impact data, etc.) associated with a user or the user’s environment from which to enhance user safety or helmet

functionality. The suspension units 20, 20' may be paired or otherwise communicatively coupled to a smart phone or other computing device to facilitate or carry out such functional enhancements. For example, suspension units 20, 20' may be worn by a group of workers on a jobsite and biometric data, such as body temperature and heartrate, may be collected and

transmitted to an associated computing device for monitoring the health and wellbeing of said workers, and, if needed, the taking of action to address any irregularities. As another example, location data may be collected and transmitted to an associated computing device for monitoring the location of said workers from which to enhance safety and jobsite compliance.

Although the aforementioned suspension units 20, 20' may be used to collect data without assistance from other sensing devices or apparatuses, in some instances, the suspension units 20, 20' may operate in conjunction with other sensing devices or apparatuses to provide additional functionality. For example, according to one embodiment, a system may be provided which includes one of the aforementioned suspension units 20, 20' and a light-emitting unit 70 removably attachable to an exterior of the

conventional helmet shell 12, which operates in parallel or tandem with said suspension unit 20, 20'. An example embodiment of such a light-emitting unit 70 is shown in Figure 4. Figure 5 shows the light-emitting unit 70

removably secured to a conventional helmet shell 12' similar to the conventional helmet shell 12 shown in Figure 1.

With reference to Figures 4 and 5, the light-emitting unit 70 may include, for example: one or more light sources 72; and a light-emitting unit control system 74, the light-emitting unit control system 74 communicatively coupled, either directly or via the computing device or network, to the control system 50 of the suspension unit 20, 20', and being configured to control the light sources 72 to emit light based at least in part on the data signal

transmitted by the communication module 54 of the control system 50 of the suspension unit 20, 20'. In this manner, the suspension unit 20, 20' may be used to collect various data and the light-emitting unit 70 may be illuminated based at least in part on said data.

In some instances, the control system 50 of the suspension unit 20, 20' may be communicatively coupled to the computing device or network via the light-emitting unit control system 74. In this manner, data may obtained by the suspension unit 20, 20', transmitted to the light-emitting unit 70 and then transmitted to the computing device or network for further processing, storage or other action.

In some instances, the light-emitting unit 70 may include one or more light-emitting unit sensors (not shown) arranged to obtain environmental, location, motion, impact and/or other data to supplement data obtained by the suspension unit 20, 20'. For example, the light-emitting unit 70 may include a temperature and/or humidity sensor from which to obtain environmental data in the vicinity of the user, which environmental data may be used to supplement and/or modify other data (e.g., biometric data) obtained by the suspension unit 20, 20' .

The light-emitting unit 70 and the suspension unit 20, 20' may be pairable with each other directly or via the computing device or network to facilitate a transfer of data from the suspension unit 20, 20' to the light-emitting unit 70 and/or a transfer of data from the light-emitting unit 70 to the suspension unit 20, 20'.
