Reference numerals: low hardness foam 1, a seat belt retractor 2, a seat belt 21, a foam support wire 3, a back frame 4, a back frame top member 41, a back frame side member 42, a back frame bottom member 43, a headrest guide bracket 44, an upper fixing bracket 5, a lower fixing bracket 6, and a dummy 7.
Detailed Description
In the following detailed description of the embodiments of the present invention, it should be noted that, in the description of the present invention, the terms "upper", "lower", "left", "right", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description and simplification of description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, fig. 3 and fig. 4, a lumbar support structure for improving whiplash and comfort includes a low hardness foam 1 and a seat belt retractor 2, the low hardness foam 1 replaces original high hardness foam and inlays on a foam support steel wire 3, comfort of a driver and a passenger can be improved through the low hardness foam 1, both ends of the foam support steel wire 3 are hung on a backrest frame 4, the backrest frame 4 includes a backrest frame top member 41, a backrest frame side beam 42, a backrest frame bottom member 43 and a headrest guide bracket 44, two backrest frame side beams 42 and two backrest frame side beams 42 are welded on both sides of the backrest frame top member 41, two backrest frame bottom members 43 are welded on the bottom of the backrest frame side beams, a head rest guide bracket 44 is welded on one side of the backrest frame top member 41 close to a human body, the head rest guide bracket 44 is used for installing a head rest, an upper fixed bracket 5 is welded on the other side of the backrest frame top member 41, two seat belt retractors 2 are bolted on both sides of the upper fixed bracket 5, two seat belt retractors 21 are provided in which the seat belt retractors 21 are connected with a lower fixed bracket 6 through bolts, and the backrest frame retractor 6 can absorb energy when the lower seat belt retractors 6 and the seat belt retractors 2 are used for absorbing soft impact.
Working process
In daily driving, because the foam on the seat adopts low hardness foam, so can greatly improve driver and passenger's travelling comfort, and the safety belt coiler in back skeleton rear also can not die the safety belt lock, and the safety belt can be free at the uniform velocity pulling.
When the vehicle takes place the striking suddenly, the driver and the passenger of front truck can be fast backward the striking under the effect of inertial force, thereby transmit the effort for low rigidity foam, low rigidity foam deformation energy-absorbing, and then reduce partly energy, and the energy that does not absorb will continue to transmit for the foam support steel wire, foam support steel wire energy-absorbing deformation, and transmit for the back skeleton through the department that articulates at both ends, and the energy that does not absorb can continue to transmit for the safety belt coiler, the safety belt coiler triggers the ratchet lock safety belt the safety belt in the safety belt coiler because the quick backward striking of human body, thereby the safety belt provides the support for low rigidity foam, the distance that the restriction human body caves in to the seat back, and the energy that the safety belt absorbs is then transmitted for the back skeleton through upper and lower both ends, thereby reduce the injury that the human body backward the striking caused to the back.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, and not to limit the same; although embodiments of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
