The specific embodiment
For technical matters, technical scheme and advantage that embodiment of the present utility model will be solved are clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiment of the present utility model is for touching after automobile in process, owing to having space between occupant's head and chair headrest, occupant's head is excessively swung back and is caused the problem of cervical injuries, a kind of Chair back cushion device is provided, can after avoid head back upset in touching process, guarantee that head and trunk are synchronized with the movement, and have prevented the generation of occupant's neck whiplash injury.
As shown in Figure 1, embodiment of the present utility model provides a kind of Chair back cushion device, comprising:
Inside is provided with the first back cushion part 1 of a plurality of gas storage pipelines 8 that are filled with gas;
Inside is provided with the second back cushion part 2 of cavity;
For when automobile bumps, the gas in described gas storage pipeline 8 is flowed in described cavity, make the volume of described the second back cushion part 2 become the status adjustment construction of switch 4 impacting with damp impacts greatly.
For bolster apparatus is fixed on automotive seat, need on seat bolster apparatus, connecting device be set, so in specific embodiment of the utility model, wherein, described Chair back cushion device also comprises: be arranged in described the first back cushion part 1, for described the first back cushion part 1 is fixed on to the first connecting device on motor vehicle seat back front side surface.And in specific embodiment of the utility model, wherein, described Chair back cushion device also comprises: be arranged at described the second back cushion and partly go up, for the second connecting device on car seat headrest front side surface by described the second back cushion partial fixing.Can Chair back cushion device is fixing on the seat by above-mentioned the first connecting device and the second connecting device, be not easy to come off.
Certain the first connecting device can be connecting band, can certainly be some other for fixing the connecting device of the first back cushion part, such as, button structure, stayed structure etc., does not enumerate at this.The second connecting device is deformable elastic connecting band, such as buckle, rubber tape, elastic cord etc., at this, does not enumerate.
For after touch while occurring, guarantee that the gas in gas storage pipeline 8 flows in the cavity of the second back cushion part 2, therefore in specific embodiment of the utility model, described Chair back cushion device also comprises: be connected in a plurality of connection pipes 3 between described gas storage pipeline 8 and described cavity; Wherein, described status adjustment construction of switch 4 is arranged at the junction of connection pipe 3 and described gas storage pipeline 8.
And connection pipe is communicated with cavity.Certainly; status adjustment construction of switch can be the partition apparatus such as stopper or holly strip; partition apparatus cuts off the gas communication in gas storage pipeline and the second back cushion part cavity under normal conditions; after touch while occurring; partition apparatus can be by manually or automatically opening; open the front junction of partition apparatus and connection pipe can being done and soften processing; with the gas in assurance gas storage pipeline, can break through partition apparatus enters in the second back cushion part cavity; the second back cushion part is expanded smoothly, protection people's neck.
But sometimes because gaseous tension in gas storage pipeline is not enough, cause gas to enter less than in cavity, and cause occupant's neck to be sprained, now can carry out structural processing to gas storage pipeline.Therefore,, in another embodiment of the present utility model, described gas storage pipeline 8 narrows from the bottom to top along back of seat.
Due to the architectural feature that gas storage pipeline narrows from the bottom to top gradually, gas speed when upwards being flowed by backrest bottom is speeded, contribute to improve air pressure, guaranteed that more reliably gas can break through smoothly partition apparatus and enter in cavity.
Below in conjunction with specific embodiment, the utility model is elaborated:
After touch before generation, as shown in Figure 2, wherein Fig. 3 is the structure enlarged drawing of the above part of connection pipe in Fig. 2.Only have in the gas storage pipeline 8 of the first back cushion part 1 and be filled with gas, the cavity of connection pipe 3 and the second back cushion part 2 keeps without gaseous state.The first back cushion part 1 is consistent with profile and the back of seat 5 of occupant back contact side, guarantees even support occupant back; Chimeric with backrest 5 contact sides and back of seat, guaranteed the stability of its position, and the first vertical both sides of back cushion part 1 are provided with connecting band, by the first back cushion partial fixing on back of seat.The second 2 of back cushion parts rule is folding, and between head rest cover 7 and headrest 6, four limits are provided with the deformable elastic connecting bands such as buckle, and connecting band is fixed on headrest bolster on headrest along upper and lower, left and right four direction.
After touch after generation, as Fig. 4, back of seat 5 travels forward, occupant pushes at back the first back cushion part 1, the upward movement that is squeezed of the gas in gas storage pipeline 8 breaks through holly strip 4 and enters in the second back cushion part 2 cavitys, until be full of via connection pipe 3.Headrest bolster 2 inflations, fill the space between occupant's head and headrest 6, and it is consistent with occupant's head contact side profile and chair headrest 6 profiles, guarantees even support occupant's head; Chimeric with headrest 6 with chair headrest contact side profile, guarantee its positional stability.After the second back cushion part 2 inflations, a little more than chair headrest 6, be conducive to like this suppress head generation Whiplash injury.For full extension after making the second back cushion part 2 inflation, open, require head rest cover 7 materials to have certain elasticity, or head rest cover 7 some position do to weaken and process, so that headrest bolster 2 is burst head rest cover 7 and reached the state strutting completely.
Above-mentioned whole process, owing to being filled between occupant's head and chair headrest 6 after the second back cushion part 2 inflations, reduced the distance between occupant's head and headrest 6, suppressed head back upset, guarantee that head and trunk are synchronized with the movement, and have avoided the generation of occupant's neck whiplash injury.
In order to address the above problem better, embodiment of the present utility model also provides a kind of automobile, and the chair headrest that comprises seat and be installed on described back of seat top, is characterized in that, described automobile also comprises:
Inside is provided with the first back cushion part of a plurality of gas storage pipelines that are filled with gas;
Inside is provided with the second back cushion part of cavity;
For when automobile bumps, the gas in described gas storage pipeline is flowed in described cavity, make the volume of described the second back cushion part become the status adjustment construction of switch impacting with damp impacts greatly.
Wherein, the corresponding laminating of back of seat of described the first back cushion part and described automobile, the partly laminating corresponding to described chair headrest of described the second back cushion.
Wherein, described automobile also comprises: be arranged at described the first back cushion and partly go up, for the first connecting device on motor vehicle seat back front side surface by described the first back cushion partial fixing.
Wherein, described the first connecting device is connecting band.
Wherein, described automobile also comprises: be arranged at described the second back cushion and partly go up, for the second connecting device on car seat headrest front side surface by described the second back cushion partial fixing.
