Example 1

The embodiment provides a safety belt device, is different from the installation of the safety belt on the B-pillar and the threshold beam of the conventional motorcycle type, because this arrangement structure relies on the B-pillar and can't be applied to the vehicle without B-pillar design, therefore, the embodiment provides a safety belt device suitable for the vehicle type without B-pillar, combines fig. 1 ~ 4, and the concrete description is as follows:

the seatbelt apparatus of the present embodiment includes: the safety belt fixing device comprises a first fixing piece 1, a second fixing piece 2, a safety belt 4, a safety belt accommodating piece 3, a first locking piece 10 and a second locking piece 20;

the first locking piece 10 is positioned between the safety belt accommodating piece 3 and the second locking piece 20, one end of the safety belt 4 is fixed in the safety belt accommodating piece 3, and the other end of the safety belt 4 penetrates through the first locking piece 10 and then is fixed on the second locking piece 20;

the first fixing piece 1 is used for fixing the first locking piece 10 and is detachably connected with the first locking piece 10;

the second fixing member 2 is used for fixing the second locking member 20, and is detachably connected to the second locking member 20.

The first locking member 10 is movably disposed on the harness strap 4; after the first fixing member 1 is connected with the first locking member 10 and the second fixing member 2 is connected with the second locking member 20, the first locking member 10 divides the harness 4 into a shoulder strap and a waist strap; wherein the shoulder straps are used for restraining the upper body of the passenger, and the waist straps are used for restraining the waist of the passenger.

In the seat belt use state, the seat belt apparatus of the present embodiment is disposed corresponding to the first fixing point 100, the second fixing point 200, and the third fixing point 300 of the vehicle body structure, and preferably, the first fixing point 100 positions the seat belt 4 on the roof side rail of the vehicle body, the second fixing point 200 fixes the seat belt 4 to the seat inner side, and the third fixing point 300 fixes the seat belt 4 to the rocker beam of the vehicle body side. The first fixing point 100 and the second fixing point 200 of the present embodiment are not arranged depending on the B-pillar structure, so that the problem that the conventional vehicle-type safety belt without a B-pillar cannot be applied can be effectively solved.

As a preferred embodiment of this embodiment, it is possible to arrange that the belt receiver 3 of this embodiment is located on the side sill of the roof panel of the vehicle body, the first attachment 1 is located on the end of the seat remote from the door side or on the floor structure, and the second attachment 2 is located on the rocker inner panel of the side wall of the vehicle body.

It should be noted that, for the comfort, the specific installation position of the belt accommodating part 3 needs to be determined according to the position of the R point of the seat, and the present embodiment is not limited in detail due to the existing vehicle and seat layout differences. It will be appreciated by those skilled in the art that the attachment location of the seat belt to the vehicle body may be adjusted as desired for different vehicle body structure designs.

As an optional implementation manner of this embodiment, the first fixing element 1 and the first locking element 10 are plug-in structures of a lock tongue and a lock catch; the second fixing element 2 and the second locking element 20 are plug-in structures of a lock tongue and a lock catch. The first fixing member 1 and the first locking member 10 fix the harness 4 to the end or the floor structure away from the door side; the second fixing member 2 and the second locking member 20 fix the safety belt 4 to the rocker inner panel of the body side.

As an alternative embodiment of the present embodiment, automatic locking devices may be provided in the first fixing unit 1 and the first lock unit 10 and the second fixing unit 2 and the second lock unit 20, and the operation burden on the driver and the passenger may be reduced by the automatic locking devices instead of manual operation.

The seatbelt apparatus of the present embodiment has two unlocked states, and the restraint of the seatbelt on the occupant of the seat can be released in both the unlocked states. The first mode is that only the lock catch at the inner side of the seat is unlocked, in an unlocked state, the safety belt accommodating piece 3 recovers part of the shoulder belt and the waist belt, and the rest safety belt is suspended between the top cover side beam and the threshold beam, so that the self getting-on and getting-off requirements of passengers can be met; the second way is that the inside and outside buckles of the seat are all unfastened, and in the unlocked state, the safety belt accommodating part 3 recovers all the safety belts, thus being matched with the structural design of the vehicle body without the upright post.

As an alternative to this embodiment, the belt receiver 3 is selected from universal retractors, preferably also comprising a locking mechanism for locking the safety belt 4 when the pulling force exceeds a limit value, in order to limit the pulled-out length of the safety belt 4. When the vehicle is impacted by the opposite side opposite to the driver seat, the passenger inclines towards the impact direction due to inertia, the safety belt device of the embodiment can effectively restrain the inertial motion of the driver and the passenger, protect the passenger from impacting hard objects in the vehicle due to too much inclination, and effectively improve the riding safety risk of the passenger.

Example 2

The present embodiment provides a vehicle including the seatbelt apparatus of embodiment 1 on the basis of embodiment 1. Due to the design of the safety belt device, when a passenger unlocks the safety belt, the vehicle of the embodiment can switch the unlocking mode according to the requirement, the first mode is to only unlock the lock catch on the inner side of the seat, and under the unlocking state, the front row personnel can get on or off the vehicle conveniently; the second mode is that the locks on the inner side and the outer side of the seat are unlocked, so that the door opening state of passengers can be ensured, and the arrangement of the safety belts does not influence the passengers on the rear row to get on or off the vehicle.

Specifically describing the first mode of use with reference to fig. 3, the occupant unlocks the seat belt only at the first fixing point 100, that is, unlocks the first locking piece 10 and the first fixing piece 1, and in the vehicle of the present embodiment, after the first locking piece 10 is disengaged from the first fixing piece 1, the seat belt accommodating piece 3 recovers a part of the seat belt 4, and the second locking piece 20 connects the remaining seat belt 4 between the rocker beam and the roof side rail.

Referring to fig. 4, the second mode of use will be described in detail, in which the occupant unlocks the seat belt at the first fixing point 100 and the second fixing point 200, that is, unlocks the first lock member 10 and the first fixing member 1 and the second lock member 20 and the second fixing member 2, respectively. In the vehicle of the embodiment, after the first lock 10 and the second lock 20 are disengaged from the first mount 1 and the second mount 2, respectively, the seat belt housing 3 recovers the entire seat belt 4, and the first lock 10 and the second lock 20 are suspended outside the seat belt housing 3.

It should be noted that, for the design of a vehicle without a B-pillar, in some scenes, when the vehicle door needs to be completely opened, a second unlocking mode is preferred, when a passenger gets off the vehicle, the first fixing point 100 and the second fixing point 200 are unlocked, the safety belt accommodating part 3 completely retracts the safety belt 4, so that the vehicle door space is given out, the arrangement of the safety belt does not influence the passengers in the rear row to get on or off the vehicle, and the loading of large goods is also facilitated.

Preferably, the vehicle of the present embodiment is a B-pillar-free vehicle body structure design.
