Abstract
The utility model relates to a rear-row seat and aims at providing a rear-row seat with the functions of avoiding the injury to the necks of rear-row passengers and reducing potential hazards. The rear-row seat comprises a rear-row seat headrest, a seat backrest and a buffer device, wherein the buffer device is respectively connected with the rear-row seat headrest and the seat backrest. The rear-row seat disclosed by the utility model has the beneficial effects that energy can be effectively absorbed in the rear collision form, so that the whiplash injury is reduced, the injury to the necks and the heads of the rear-row passengers is avoided and the potential hazards are reduced.
Description
Technical field
The utility model relates to a kind of automotive seat, especially relates to a kind of back seat.
Background technology
Along with the development of science and technology, people's consumption idea is also in continuous improve, and the integral body of automobile requires more and more higher, and the people requirement of seat not only are only limited to the requirement of traveling comfort, and more pay close attention to safety performance.Be accompanied by the continuous increase of traffic accident, vehicle safety performance more and more obtains paying attention to, as the rear collision form of one of safety traffic hidden danger, it is more outstanding for the injury of occupant's neck to have occurrence frequency higher, heavier to occupant injury characteristics, particularly a seat.Especially for the occupant who rides in rear row, back seat does not often possess the effect of buffer shock-absorbing, thereby easily causes larger injury.
Chinese patent Granted publication number: CN 201756077U, Granted publication day is on March 9th, 2011, discloses a kind of back seat with the headrest of having a rest, and comprises cushion frame, the chair back and seat support, the inferior horn place of the described chair back is provided with chair back breach, and described chair back indentation, there is embedded with headrest.The weak point of this utility model is that this back seat can't be avoided rear row occupant's cervical injuries when running into the rear collision form of one of safety traffic hidden danger, have larger potential safety hazard.
The utility model content
The utility model is can't avoid cervical injuries to rear row occupant in order to overcome back seat in the prior art, has the problem of larger potential safety hazard, and a kind of cervical injuries of avoiding rear row occupant is provided, and reduces the back seat of potential safety hazard.
To achieve these goals, the utility model is by the following technical solutions:
A kind of back seat of the present utility model comprises back seat headrest, back of seat and shock absorber, and described shock absorber connects respectively back seat headrest and back of seat.
Described shock absorber connects respectively back seat headrest and back of seat; when running into the rear collision form of one of safety traffic hidden danger; occupant's head on the back seat and neck location are subject to impact effect on the back seat headrest; back seat headrest by shock absorber will be suffered collision the time energy absorbing to back of seat, thereby the safety of arranging the occupant after the protection.Design has reached the cervical injuries of avoiding rear row occupant like this, reduces the purpose of potential safety hazard.
As preferably, described shock absorber comprises that at least one has elastomeric pole, and in the forms of collision, the actv. absorbed energy reduces whiplash injury in the back.
As preferably; described pole is the obtuse-angulate knee of bending; described pole material is rubber; described pole is bent into the obtuse angle from the centre; employing has the pole of certain sinuousness; so that the contact between back seat headrest and the occupant's head is more comfortable, also be conducive to protect occupant's head and neck by pole.
As preferably, described shock absorber comprises at least one pneumatic bomb spring base, described pneumatic bomb spring base comprises air cylinder and portable bar, described air cylinder connecting chair backrest, described portable bar connects the back seat headrest, in the forms of collision, the actv. absorbed energy reduces whiplash injury in the back.
As preferably; described back seat headrest is provided with pipe link; the portable bar of described pneumatic bomb spring base is provided with coupling link with the end that the back seat headrest is connected; described coupling link is socketed on the pipe link; adopt the pneumatic bomb reed pipe automatically to regulate the position of back seat headrest and back of seat; can protect occupant's head by actv., so that the contact between back seat headrest and the occupant's head is more comfortable, also be conducive to protect occupant's head and neck.
The beneficial effects of the utility model are: in the forms of collision, the actv. absorbed energy reduces whiplash injury in the back, avoids rear row occupant's neck and the injury of head are reduced potential safety hazard.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is part-structure scheme drawing of the present utility model;
Fig. 3 is another kind of part-structure scheme drawing of the present utility model.
Among the figure: 1. back seat is rested the head on, 2. back of seat, 3. shock absorber, 4. portable bar, 5. air cylinder, 6. pipe link, 7. coupling link.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment one: among the embodiment as shown in Figure 1 and Figure 2, a kind of back seat comprises back seat headrest 1, back of seat 2 and shock absorber 3, and described shock absorber 3 connects respectively back seat headrest 1 and back of seat 2.Described shock absorber 3 comprises that two roots have elastomeric pole, and described pole is bent into the obtuse angle for the obtuse-angulate knee of bending from the centre, and described pole material is rubber.
Because back of seat 2 is uncontrollable generally speaking, for the concern of back of seat 2 intensity not yet considers whip performance at present, so the energy-absorbing effect of seat is not very desirable.Back seat headrest 1 adopts to have the pole that is bent into the obtuse angle from the centre and is connected with back of seat 2, and so, in the collision process, pole can bear the impact of head in the back, and the while can absorbing impact energy, reduces whiplash injury.Test the static measurement requirement with reference to front-row seats for whipping; back seat headrest 1 is wanted≤40mm with the horizontal throw of testing dummy's head; can effectively reduce the relevant injury values of head and neck; in like manner; the pole that back seat headrest 1 connects is bent into the curved design at obtuse angle from the centre; so that the contact between back seat headrest 1 and the occupant's head is more comfortable, the protection effect for occupant's neck is apparent in view so effectively.
Embodiment two: in Fig. 1, embodiment shown in Figure 3, a kind of back seat comprises back seat headrest 1, back of seat 2 and shock absorber 3, and described shock absorber 3 connects respectively back seat headrest 1 and back of seat 2.Described shock absorber 3 comprises two pneumatic bomb spring bases, and described pneumatic bomb spring base comprises air cylinder 5 and portable bar 4, described air cylinder 5 connecting chair backrests 2, and described portable bar 4 connects back seat headrest 1.Described back seat headrest 1 is provided with pipe link 6, and the portable bar 4 of described pneumatic bomb spring base is provided with coupling link 7 with back seat headrest 1 end that is connected, and described coupling link 7 is socketed on the pipe link 6.
