Description
Technical field
The utility model relates to vehicle passive safety technical field, especially relates to a kind of anti-whiplash injury seat framing structure.
Background technology
Motor traffic accidents has become the large public hazards that the world today threatened, tortured the mankind.Traffic accident not only causes huge personal casualty, returns the whole world and brings huge economic loss.In various types of vehicle traffic accident, human body head and neck is the most common position of causing injury, and this is particularly common in the rear-end impact of automobile.In rear-end impact, the ratio of cervical injuries is up to 77.1%.Neck injury, is called whiplash injury under normal circumstances, specially refers to that Motor vehicle rear-end crash produces unexpected hyperextension to occupant's neck and crosses and bends application force, make neck soft bear unfair stress and the damage that causes.It often can cause multiple and long-term illness; as headache, tired, dizzy, absent minded, cervicodynia and neck and shoulder ache etc.; though the symptom that whiplash injury causes can not cause life danger, medical expense is high, and may produce long-term, obvious sequelae.Automotive seat are as important support and protecting component, even more important to the support of passenger when colliding generation, but current armchair structure is when rear-end impact occurs, can not play good supporting role to head of passenger, the whiplash injury caused by rear-end impact happens occasionally.
If Chinese Patent Application No. is 201320562946.8 disclose a kind of translational energy-absorbing seat for whiplash injury anti-under rear-end impact, the translational energy-absorbing mechanism comprising chair headrest, back of seat, seat chair cushion, the slide rail be fixedly connected with described seat chair cushion, the fixed guide be fixedly connected with automotive floor panel, the lockable mechanism of adjusting seat front and back position, the regulating handle of adjusting seat front and back position and be arranged on below described seat chair cushion, described translational energy-absorbing mechanism is arranged symmetrically in the both sides of described seat.Although above-mentioned patent realizes the object of anti-whiplash injury by the improvement of base, complex structure, impact assembling.
Utility model content
Given this, the purpose of this utility model is to provide a kind of novel anti-whiplash injury seat framing structure, and make when there is rear-end impact, chair headrest can provide more efficiently support and protection for head of passenger, thus reaches the object reducing whiplash injury.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of anti-whiplash injury seat framing structure, comprise support body, be arranged on the S shape spring at support body backrest place, be symmetricly set on two rotating shafts on support body top, connect the rotating shaft adapter plate between two rotating shafts, and be arranged on the backrest depression bar be connected on rear side of S shape spring and with described rotating shaft.The upper end of above-mentioned backrest depression bar is also provided with adjustable head pillow frame.In order to ensure the reset of backrest depression bar after rear-end impact occurs, the retracing spring offseted being installed between two rotating shafts, by the recuperability effect of retracing spring, realizing the reset of backrest depression bar, to ensure that seat can repeated usage with backrest depression bar.Adopt technique scheme, the pressure of passenger-back during collision is converted to bearing force to head of passenger by backrest depression bar, rotating shaft and retracing spring, originally the mode of motion being harmful to passenger is converted into actv. support, effectively reduces because rear-end impact causes the injury of whiplash injury.
In order to ensure that Cai passenger-back contacts with backrest depression bar, the gap between backrest depression bar and S shape spring is 5 ~ 10mm only when rear-end impact occurs.Support body is equiped with front limit bar and rear position-limited lever respectively before and after backrest depression bar, wherein, front limit bar is for limiting the gap of backrest depression bar and S shape spring, and rear position-limited lever ensure that when rear-end impact occurs, and it is excessive that backrest depression bar is unlikely to distortion.
Head pillow frame is formed by round steel bending and welding manufacture, and the head pillow frame after having welded is arranged on support body by the headrest conduit of backrest depression bar upper end.Backrest depression bar is formed by bend pipe bending, backrest depression bar top after bending is welded with rotating shaft, realizes being synchronized with the movement of backrest depression bar and rotating shaft, and backrest depression bar top is integrated with the function of headrest conduit, by the up-down adjustment of guide rod of resting the head on, realize the up-down adjustment of head pillow frame.Rotating shaft is made up of cast steel, and two ends fitting surface must through machinework to ensure that it installs quality of fit, and rotating shaft round end is installed in support body two ends, coordinates by the axial plane of both ends of the surface the rotation realizing head pillow frame frame body upper end.In order to limit head pillow frame and rotating shaft other motions except rotating, ensure the synchronous axial system of two rotating shafts simultaneously, two rotating shafts are respectively equipped with shaped face near rotating shaft adapter plate side, by the cooperation of shaped face, limit the relative motion between rotating shaft adapter plate and rotating shaft.For the ease of installing, rotating shaft adapter plate divides upper and lower two parts, and adopts bolt to fix.
The beneficial effects of the utility model: the utility model by backrest depression bar, rotating shaft, retracing spring, rotating head pillow frame, original fixed head pillow frame is converted into can frame body rotate mechanism.When rear-end impact occurs, passenger due to the effect of force of inertia, whole trunk by after move, now occupant's back pressure is comparatively large, moves after larger back pressure compression backrest pull bar, thus drives head pillow frame to rotate forward.Due to head of passenger after move past in journey, the support of the chair headrest moved forward, the neck hyperextension caused by rear impact and power excessively in the wrong will reduce greatly, thus reach the object reducing whiplash injury, and structure is simply convenient to implement, what the setting of retracing spring ensure that structure can reusing.
Below with reference to drawings and Examples, the utility model is described in detail.
