Abstract
The utility model discloses an anti-whiplash automobile seat back. According to the anti-whiplash automobile seat back, both sides of a seat back and the side edges of a seat are provided with grooves, which separate the seat back from the side edges of the seat; stress expanding structures are arranged inside the grooves and composed of flexible cloth which is folded into a V shape; the V-shaped flexible cloth is filled inside the grooves, both sides of the V-shaped flexible cloth are connected together with the side edges of the seat back and the seat. When low-speed back collision occurs, the seat back moves backwards, and the stress expanding structures can be unfolded, so that the back of a passenger can be fully recessed inside the seat back, the head and the body of the passenger can move backwards at similar speeds, further the relative accelerations of the head and the body can be reduced, and the anti-whiplash effects can be obtained. The anti-whiplash automobile seat back achieves the anti-whiplash effects and meanwhile is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of automotive seat, particularly a kind of motor vehicle seat back of whipping of preventing.
Background technology
The seat anti-whip system using at present is mainly divided two large classes: the SAHR one, realizing by mechanism, tests headrest and waist holder to link to play the protective effect to chaufeur while hitting after low speed to realize by mechanism; Two, active backrest increases mechanism and spring on backrest frames, after while hitting, back of seat is rotated around a certain axle, in rotary course, headrest more approaches people's head, plays the object of protection chaufeur.
Above-mentioned seat anti-whip system architecture complexity, cost is high.
Utility model content
The purpose of this utility model is to provide a kind of novel motor vehicle seat back of whipping of preventing.
The utility model is to offer groove between the both sides of back of seat and the side of seat, groove will separate between back of seat and the side of seat, in groove, be provided with stressed deployed configuration, stressed deployed configuration is to be made up of the flexible cloth of folding forming V-shape, the plug of the flexible cloth of V-arrangement is in groove, and the dual-side of the flexible cloth of V-arrangement links together with the side of back of seat and seat respectively.
Attractive in appearance for seat is coated with elastic fabric in side grooves, and the side seams of the both sides of elastic fabric and back of seat and seat is combined.
Article two, the back side of stressed deployed configuration links together with two bands.
The material of the side of described back of seat and seat is foamed materials.
The utility model prevents that the principle of whipping from being:
The utility model is provided with stressed deployed configuration, in the time hitting after generation low speed, back of seat moves backward, stressed deployed configuration is opened, make occupant back fully be trapped in back of seat inside, occupant's head and health are moved backward with approximately uniform speed, therefore reduced the relative acceleration of head and health, played the effect of anti-whip.
The beneficial effects of the utility model: the utility model is a kind of novel seat anti-whip structure, and in anti-whip, simple in structure, cost is low.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the present embodiment is to offer groove 2 between the both sides of back of seat 1 and the side of seat 3, groove 2 will separate between the side of back of seat 1 and seat 3, in groove 2, be provided with stressed deployed configuration 4, as shown in Figure 4 and Figure 5, stressed deployed configuration 4 is to be made up of the flexible cloth of folding forming V-shape, and the plug of the flexible cloth of V-arrangement is in groove 2, and the dual-side of the flexible cloth of V-arrangement links together with the side 3 of back of seat 1 and seat respectively.
Attractive in appearance for seat is coated with elastic fabric 5 in side grooves 2, and the side 3 of the both sides of elastic fabric 5 and back of seat 1 and seat is stitched together.
Article two, the back side of stressed deployed configuration 4 links together with two bands 6, as shown in Figure 4 and Figure 5.
The material of the side 3 of described back of seat 1 and seat is foamed materials.
The present embodiment prevents that the principle of whipping from being:
The utility model is provided with stressed deployed configuration, in the time hitting after generation low speed, occupant will move backward, occupant's back will promote back of seat and move backward, deployed configuration is opened, and makes occupant back fully be trapped in back of seat inside, and occupant's head and health are moved backward with approximately uniform speed, therefore reduce the relative acceleration of head and health, played the effect of anti-whip.
