Description

Safety device for vehicles

The invention relates to a safety device for vehicles for the protection of occupants in the event of an impact. The invention thus relates to a development that significantly increases safety in vehicles of all kinds without sacrificing comfort.

Motor vehicles today consist of a self-supporting body or a body, which is connected to a frame.

The seats and most of the controls are fixed to the body. As a result, the individual operating elements and the seats in their relative positions to one another change in the event of an accidental deformation. which leads to an enormous risk of injury (pedigree penetrates into the footwell, steering wheel to the chest-head area).

The side area of vehicles is still a big weak point, although the modern bodies can already absorb a lot of energy in the side area. However, due to the design, it will always be difficult to improve it, as there is simply a lack of space to absorb the energy. The risk of injury here is especially in the entire side of the occupant.

The monocoque known from motorsport is known for its safety and contributes to a considerable occupant protection, but these constructions have the following disadvantages: The entry is difficult and the comfort is not suitable for everyday use. The monocoque shell is also firmly connected to the body. In the event of damage, this connection should break or come loose, which in turn means that the monocoque can move uncontrollably in the passenger compartment and endanger other passengers.

The invention has for its object to provide a safety device that provides a significantly higher occupant protection in all types of vehicles that are surrounded by a body.

The object is achieved by a safety device comprising a seat receptacle which carries the seat. The seat receptacle is displaceable in particular in a substantially horizontal plane in the vehicle so as to at least move away or move away the seat and thus the person to be protected from the impact area in the event of an impact. This seat mount is mounted on the chassis or the floor assembly so in the accident event the seat, and thus on to move the seated person away from the accident area. The invention can be used in a car, a bus, a truck or even an aircraft.

An essential advantage of the invention is that it is provided in a variant according to the invention that the seat receptacle is displaceable or movable in a substantially horizontal plane in the vehicle. It is an object of the invention to bring the person to be protected from the impact area, that is, it is already sufficient lateral displacement, away from the accident event, to achieve the success of the invention. By the arrangement of the invention such that the seat receptacle is movable in a substantially horizontal plane (of course, the seat and the seat is sufficiently stationary in the normal use of the vehicle), an optimal occupant protection in both a side impact as well as a frontal accident or a diagonal accident event (for example, obliquely from the front of the fender) guaranteed. All these very different types of accident can be countered by a variant according to the invention reliably and substantially the same effect. The invention is far more variable than the known side impact protectors, which are designed only for protection in a side impact, ie at right angles to the longitudinal extent of the vehicle, and only act linearly.

The invention does not exclude that the person to be protected is also displaced up or down, such movement is then superimposed on the lateral displacement in the horizontal plane. But it is cheaper to act without such a vertical offset in the accident event, since the vehicle height, of course, this height must hold and the vehicle is therefore to build accordingly larger, although that would not be necessary in normal operation. The realization of the safety device according to the invention therefore also causes no higher body of the body and therefore avoids correspondingly higher wind resistance of the thus formed, inventive vehicle.

In a preferred variant of the invention it is provided that the seat receptacle can be displaced against a force holding the seat receptacle in a preferred position. One idea of the invention is that it has been recognized that a continuous rigid connection between the vehicle and the seat (when placed on the seat position subbeams) results in the damaging event, for example, moving the pedals or steering wheel into the accident person and hurt them additionally. If, however, the seat upholstery is now flexible, movable, in particular displaceable in the vehicle against a force holding the seat upholstery in a preferred position, then there is the possibility, for example, when working off peak forces, such as occur without problems in an accident, for example. then to offset the seat in the sense of the invention such that the person is exposed to no or less impact influences.

According to the invention it is provided that the seat support is regularly moved linearly in case of impact, of course, the direction of movement is away from the place where the damaging event, ie the impact happens. The invention is, however, not limited thereto. It is quite possible in the context of the invention that the seat receptacle in the event of an impact about a substantially vertically oriented axis is rotatable or rotatable. In this case, for example, the linear movement is superimposed with the rotational movement. This rotation also causes the person to be protected from moving away from the damaging event, the rotational movement itself is then preferably in a substantially horizontally oriented plane. It is clear that the terms "vertical" and "horizontal" are surrounded by a corresponding tolerance interval (eg 10 °, 20 °, 30 ° or 45 °), since the effect according to the invention naturally also occurs in a wider angular range.

In this case, this movement can be active (eg, drives controlled by impact or acceleration sensors, such as explosion drive or propellant charges) or passive (eg, by the kinetic energy of the object triggering the accident - for example, an impacting motor vehicle).

Preferably, the displacement movement is derived from the impact event. As a result, this movement is carried out passively and skillful arrangement is thereby ensured that the seat receiving always away from the damaging event, so the impact area passes. Especially in the preferred arrangement of the invention, such that the seat mount is movable in a plane, a plurality of sensors are provided on the vehicle to ensure the actively assisted movement of the seat in the right direction away from the impact event or impact area.

Cleverly, a limitation is provided for the length of the sliding movement. It may, for example, be a stop or a continuously deforming material area, thus reaching a limit, thereby ensuring that the person to be protected is not injured during the sliding movement by pushing into another vehicle area. In addition, the destruction of deformation energy or impact energy is also possible by limiting the displacement movement.

Cleverly provided in a variant of the invention that both before and after the sliding movement between the seat and the vehicle connection consists. The arrangement is designed to be sufficiently stable in order not to risk tearing out of the seat receptacle and a resulting uncontrolled movement of the seat receptacle in normal damaging events.

The invention is in a preferred variant of the fact that the safety device is formed by a flexible or plastically deformable connection between the seat and the vehicle. In this flexible or plastically deformable connection between the seat and the vehicle, namely on the seat receptacle (for example, between seat and seat or seat and vehicle), several options are offered to destroy by targeted deformation kinetic or other energy and so from the Keep away from the person to be protected. Moving the seat also destroys energy, as it is no longer available for influencing the person. Ultimately, the corresponding compounds, the various materials, are sacrificed to protect the person. In particular, a deformable connection between the seat receiving and the vehicle is provided, wherein there is a large possibility of variation in the realization in this area.

The connection between the seat receptacle and the chassis / floor assembly is designed such that the relative position of the seat receptacle relative to the chassis at normal forces as z. B. when braking and accelerating, do not change. However, the connection allows movement of the seat when abnormally high forces occur (such as when hitting an obstacle or object).

For the storage or the connection between seat and chassis / floor assembly, the invention proposes several variants: a) seated on stilts seat. The stilts bend in the fall event. This deformation destroys energy and brings the seat intake away from the accident event.

b) "floating" seating of seating by sufficiently stiff springs or dampers (to destroy the impact energy).

c) bearing the seat receptacle such that the seat receptacle can perform at least one linear evasive movement, better of course an evasive movement in a plane.

d) Between the chassis / floor assembly and seat mounting a hole guide is provided. For example, a bolt on the chassis / floor assembly engages a bore of the seat mount (or vice versa). The diameter of the hole is larger or much larger than the diameter of the bolt. This results in limited in the area movement between seating and chassis or floor assembly. The force with which the seat receptacle and chassis or floor assembly are pressed together can be adjusted by the bolts. Advantageously, an elastic element, for example a spring, in particular a spring ring, is provided between the head of the bolt and the first plate. This elastic element pushes the seat against the chassis / floor assembly, thus increasing the friction between the two. In the event of an impact, the impact energy is dissipated by the friction of both parts.

Of course, the above measures can also be combined. In addition, it is possible to provide corresponding energy destruction facilities, e.g. B. deformation of end stops in the evasive movement of the seat, etc. to provide. The invention includes a wide range of implementation possibilities. It excludes, for example, an exclusively linear, rectilinear displacement of the seat intake. For example, it is provided that in case of impact, the seat holder, for example, longitudinally or laterally or transversely offset and the seat also includes the controls, such as the pedals or the steering wheel, and so these elements in their relative position to the vehicle seat or the person no or hardly a situation change experienced. Of course, such an arrangement may also be beneficial in frontal impact events, since then the entire unit of seat assembly with pedals is displaced forward or backward, for example, to avoid the impact event. It is clear that with such an arrangement, the risk of pushing the controls into the person is greatly reduced, if not excluded. Of course, it is possible to realize the relatively complex trained seat mount, with the operating units, even in a plane movable and so to achieve the same effect.

In a variant according to the invention it is provided that the seat receptacle on the vehicle is not rigidly arranged, but the arrangement is constructed so that the seat receptacle overcoming a certain holding force relative to the vehicle displaced, that is "floating". By overcoming this holding force or force is also destroyed energy from the impact event, but at the same time held the seat in a normal situation of use at the desired position. It is possible that additionally by the friction of seat and vehicle to each other, the impact energy is at least partially destroyed.

Furthermore, it is favorable that the force with which the seat receptacle is pressed together on the vehicle, is adjustable to for example, to give different users a certain possibility of adjustment. Under certain circumstances, in a lighter person, this force is slightly lower, in order to safely move away from the impact area in the event of a damaging event.

The development described below is based on a design remotely similar to a monocoque. The differences are that, on the one hand, it blends harmoniously into the shape of the passenger compartment, thus in no way restricting the suitability for everyday use, and on the other, better protecting occupants in the event of body deformation. To achieve this, it is advantageous to be able to open them in the side area, so that the comfortable entry is guaranteed as usual. The area to be opened can be integrated into the door and is non-positively connected to the safety cell when the door is closed.

The controls are designed in terms of their arrangement as in a normal vehicle, their function hereby ensured by flexible connections.

The design is intended to prevent the dimensions between the individual controls and the seat in the event of an accident change significantly, which is not true in today's bodies. In the construction but also additional compression points can be incorporated, which allow a collision in a controlled compression with the best possible occupant protection. This construction is designed to accommodate the entire body of the occupant. The outsides facing components are particularly reinforced.

Of course, it can also be equipped with extremity airbags as well as head airbags and all other options. The structure itself is flexibly connected to the vehicle back or evasive to the direction of energy, whereby it can change its position in the vehicle in the event of accidents. The connecting elements of the body to the construction are designed such that an optimal limitation of the avoidance path is given. Thus, the fallback area of the construction is defined and limited. The evasive movement can by direct force, z. B. deformation of the body or supported by crash sensors (eg, propellant charges similar to the belt tensioner).

Example: Side damage

An object (eg tree) penetrates into the side area of the body. The sill, the floor assembly and the door absorb energy through deformation. This body area is usually protected by the thickness of the door with about 15-17 cm depending on the model. Even at low impact velocities, it can be observed that the deformation develops up to the occupant area. Especially small vehicles are disadvantaged due to their external dimensions. If you provide z. B. a small car with the construction on 8 cm flexible connectors, it will be found under the same accident conditions that the entire construction with the occupant as described above is moved directly out of the danger area. The vehicle-neutral deformation range of the vehicle alone is thereby increased by approx. 50%. Through the free space thus gained, the energy intake can increase disproportionately to the penetration depth again, without endangering the occupant.

The method of manufacture and execution of the safety cell can be made of a variety of materials such. As CFK as in the proven monocoque, but also made of metal similar to a lattice frame. Of course, every seat in the vehicle equipped with this safety cell. The evasive movement can be accomplished by different structural variants, such. B. floating with spring preload or on a kind of stilts, which can bend away at high energy and at the same time limit the length of the escape route by their height. The evasion area of the connection must be at least 90 ° horizontally, in order to simultaneously ensure frontal and lateral damage to relocate the structure.

Conclusion. The installation of such a construction can further reduce the risk of injury and thus save lives.

The concrete design of the seat differs very much from that of a known monocoque. In fact, it is sufficient that the seat receptacle only in the area to the outside has a corresponding stiffening or side wall to z. B. accident events that are made frontally or from the side to be able to record accordingly. Since no side walls of the seat receptacle are provided in the interior, the comfort and the interior design of the vehicle is not affected.

It has been described that the sliding movement of the Sitzaufnähme can be done either active or passive. In particular, in the passive realization of a variant of the invention is proposed that at least one handlebar is provided on the seat structure and the handlebars to the outside of the vehicle or the handlebar is connected to a body outer part. In general, the body outer part is bent in the event of an accident to the inside. This force, which is directed at the middle area of the vehicle, is picked up by the handlebar and transmitted to the seat receiver, which is then also displaced in a direction away from the impact movement. It is favorable that the link is formed of deformable material. The possibility of deformation of the handlebar results in an energy destruction in the event of an impact. In this case, of course, the connection areas between the handlebar and the seat, such as the connection area between the handlebar and body outer part, to consider, as well as in these areas in the impact energy can be destroyed by deformation. The handlebar, for example, is also compressible. The course of a damaging event using the invention could look like this. By the impact event acts on the handlebar, which initiates the dislocation movement of the seat, the force acting here is greater than the force that holds the seat assembly in the vehicle in the preferred position, the seat assembly is moved relative to the vehicle and then, for example a corresponding stop or a limit postponed. In all these steps, work is needed, so destruction energy or impact energy destroyed. If the seat has arrived in its final position, which is due to the design due to the "floating storage" is given, the now available deformation energy is absorbed by the handlebar, which is deliberately deformed and destroyed. Only if there is a residual energy then this may possibly act on the resting person on the seat of the seat. By the handlebar another security element is realized.

Seat according to the invention.

1 shows a section of a vehicle with a safety device 1 according to the invention, wherein the safety device 1 consists of at least one seat 2 and one seat seat 3 carrying the seat 2. The seat receptacle 3 is connected to the vehicle 4 such that it is moved away in an impact from the accident area.

According to the embodiment shown in FIG. 1, the seat receptacle 3 consists of a carrier 5, on which the seat 2 is fixedly arranged according to a first embodiment or slidably according to a further embodiment in the longitudinal direction of the vehicle. For example, the carrier 5 consists of rails or a plate which carries rails, so that the seat 2 is displaceable in different locking positions.

According to a further embodiment, it is also possible to position the seat 2 in a direction transverse to the vehicle longitudinal axis. The essence of the invention, however, is that the seat support 3 relative to the vehicle 4, for example, the body, the floor assembly and / or the chassis is arranged flexibly, so that the seat holder 3 together with the seat 2 and the person to be protected in case of Impact is moved away from the accident area. For this purpose, the seat 3 is connected via a movable connection with the vehicle 4. According to the embodiment shown here stilts 6 are provided, which bend or buckle in the event of an impact and so move the seat by at least a few inches. Bending or buckling causes the impact force to energy is not fully transferred to the seat 3, but added by the stilts 6.

In FIG. 1, the seat 2 is moved from position 1 to, for example, position 2. The reference numeral 7 designates the body, the floor assembly or the chassis of the vehicle 4, and 8 designates the door which is intended for entry into the vehicle 4.

FIG. 2 shows a further exemplary embodiment of the safety device 1 according to the invention. (The same parts are provided with the same reference numerals.) According to the embodiment shown in Fig. 2, the seat receptacle 2 consists of a security cell 9, which surrounds the seat 2 from below and at least on one of the sides. The side part 10 of the security cell 9 is integrated here, for example in the door 8 and forms with the security cell 9 in the closed state of the door 8 a frictional connection. For boarding in the vehicle 4, the side panel 10 can swing together with the door 8, but finds with closed door 8 sufficient locking with the cell 9. In an impact against the door 8, the seat holder 3 and the security cell 9 is moved as a whole. This is shown in two different positions. Position 1 shows the seat receptacle 3 or safety cell 9 with side part 10 and position 2, the seat receptacle 3 'or safety cell 9' and side part 10 '. This embodiment has over the embodiment of Fig. 1 has the advantage that even in an impact at the level of the door 8, the force acting on the side part 10 of the cell 9, is transmitted to the part of the cell 9, located below the seat and thus shifts the security cell 9 together with the seat.

According to the embodiment shown here, the displacement movement takes place in a plane. According to this embodiment game the Sitzaufnähme 3 is moved relative to the body or the chassis 7.

Fig. 3 shows a third embodiment of the safety device according to the invention 1. According to this embodiment, a bottom group 11 is shown below the seat 3. According to this embodiment, the seat holder 3 is moved together with the side part 10 relative to the bottom group 11. In the embodiment of the seat receptacle 3 shown here in FIG. 3, it can be seen that the seat receptacle 3 is substantially trough-shaped. It is also a variant of the invention that the seat receptacle 3 with the stable side part 10, which is arranged for example in the door, at least frictionally, if not positively connected and thus experiences a linkage. The side part 10 is for example part of a security cell. It is arranged for example in the vehicle door.

FIG. 4 shows the side view of a vehicle 4. The seats 2 are arranged on the seat receptacle 3. As can be seen in dashed form, the seat receiving side parts 10, which should protect the person from the side. The seat 3 is connected via the stilts 6 with the vehicle 4 and the body 7 of the vehicle 4 or directly to the chassis. As can be seen, the seat receptacle 3 is formed by a safety cell 9, which receives, for example, the front and the rear seat. The safety cell 9 surrounds the leg portion of the front seat also from above, so that the legs and knees of the person to be protected from impact are protected. Advantageously, the control elements 12 of the vehicle 4 are also supported by the safety cell 9, so that the relative distance between the seat 2 and operating elements 12 is not changed in the event of an impact. This has the advantage that the controls 12 can not hurt the person too much. The connection between control ments 12 and the remaining part of the vehicle 4 is designed to be flexible, so that the controls 12 relative to the rest of the vehicle 4 are indeed displaceable, but not break. As control include pedals and / or steering wheel with steering column.

According to a further embodiment, predetermined breaking points between control element 12 and vehicle 4 are provided, so that upon a movement of the seat receptacle 3, the connection between the control element 12 and the rest of the vehicle is interrupted. The seat receptacle may not only be formed of a support 5 or a safety cell 9, but it may also be formed of an intermediate block, a frame, or even a monocoque and the like.

As can be seen in Fig. 5, the seats 5 are slidably mounted in the direction of the vehicle longitudinal axis on rails 13, so that the seating position of the seat 2 to the vehicle 4 and to the controls 12, such as pedals, steering wheel and / or gear, arbitrarily adjustable is. As can be seen, the seat receptacle 3 surrounds respectively a front and a rear seat, wherein the side is open to the adjacent seat. The safety cell 9 is made of carbon fiber reinforced material, for example.

6 shows a vehicle with the safety device according to the invention from above. The seat receptacle 3 is also formed here by a safety cell 9, which surrounds the seat 2 from below and from two sides. The front side 14 of the security cell 9 protects the person in the leg area and the side part 10 in the area of the side of the person who faces the vehicle door 8. The side part 10 is divided into an area 10 a, which is fixedly connected to the part of the security cell 9, which is located below the seat 2 and the front part 14 of the security cell 9 and a portion 10 b is movable relative to the remaining area of the safety cell 9 and only forms a unit with the safety cell in the closed state of the door 8 of the vehicle 4.

The opening area 10b is connected to the security cell 9 via locking means. In case the door 8 of the

Vehicle 4 is opened, the area is unlocked and swung open with the door 8.

Fig. 7 shows a vehicle 4 in side view. The seat receptacle 3 is formed by a safety cell 9, which surrounds a seat 5. The safety cell 9 extends below the seat, surrounds the foot area of the person to be protected and extends behind the seat into the area above the headrest of the seat 5. This embodiment is shown in plan view in Fig. 8 again, it being recognized that the side area is kept free to the adjacent seats. This has the advantage that the security cell 9 does not interfere with the occupants of the vehicle. Visibility is all around and people can talk to each other without any problems.

FIGS. 9 and 10 show a further embodiment of the safety device 1 according to the invention. The seat receptacle 3 and floor assembly consist here, for example, of two superposed plates 15 and 16, each having holes 17. The holes are aligned. The plates 15, 16 are connected by bolts 18.

According to FIG. 10, the bolt has a shaft 18a and a bolt head 18b. The diameter of the bolt shank 18a is substantially smaller and the head 18b of the bolt 18 is greater than the diameter of the holes 17. By the bolt 18 are countered by a nut 19 - both plates 15, 16 pressed together. The force with which the plates 15, 16 on each other are pressed so large that during normal motion of the vehicle, even when braking or accelerating, both plates remain on top of each other, but in an impact, so if the force is much larger, are shifted from each other. The movement is limited by the size of the holes. In order to meter the force with which the plates 15, 16 are pressed against each other, elastic means are provided between the bolt head 18b and plate or nut 19 and plate 16, which are designed here as a spring ring 20. According to a further embodiment, compression springs or other elastic means such as rubber material and the like can also be used here.

According to the embodiment of FIG. 11, the bolt is fixedly connected to the lower plate 16 and the upper plate 15 is clamped by means of a nut 19 and the spring ring 20 against the lower plate 16.

According to a further embodiment, the bolt 18 can also be screwed into bag-shaped holes in the lower or upper plate 16. Between the bolt head 18b and upper plate 15, an elastic material is again provided. This embodiment is not shown in the figures, but is also to be embraced by the invention.

Fig. 12 shows another embodiment of the invention. The seat receptacle 3 is held by sufficiently stiff springs 21. These springs 21 allow the seat receptacle 3 is moved away in an impact from its position. However, it is necessary that spring-back to attenuate much more, to prevent that springs back by a countermovement seat. The illustrated springs 21 may also be formed by dampers, rubber dampers or shock absorbers.
