Above-mentioned waist is a kind of embodiment by the annexation of stay bearing plate 61 and fixed support 65, also can be following a kind of situation: described waist is fixedly connected on the fixed support 65 by the end near second cross bar 66 of stay bearing plate 61, and waist is slidingly connected on the fixed support 65 by the end away from second cross bar 66 of stay bearing plate 61.
Above-mentioned lumbar support apparatus 6 is under normal operation, has the lumbar support regulatory function, specifically: motor 62 is by drag-line 64, driving waist slides on fixed support 65 by stay bearing plate 61, thereby make waist lean on stay bearing plate 61 to heave, be that waist leans on stay bearing plate 61 to move towards the occupant waist direction, reach the effect of support passengers waist.
Further, aforementioned link mechanism 5 is by first connecting rod 51, second connecting rod 52, third connecting rod 53 and the 4th connecting rod 54 are formed, one end of first connecting rod 51 is connected on corresponding curb girder 3 inboards by rotating shaft 7, being provided with elastomeric element 8 elasticity between an end of first connecting rod 51 and rotating shaft 7 is connected, the other end of first connecting rod 51 and second connecting rod 52 1 ends are hinged, third connecting rod 53 respectively with the other end of second connecting rod 52, curb girder 3 is hinged, third connecting rod 53 is also captiveed joint with waist rest device 6, these third connecting rod 53 middle parts have a hole 9, the 4th connecting rod 54 1 ends are by pin that can slide in the hole 9 of third connecting rod 53 10 and third connecting rod 53 sliding block joints, and the other end of the 4th connecting rod 54 is hinged with corresponding curb girder 3.
In sum; and in conjunction with the accompanying drawings; learn that principle of work of the present utility model is: when vehicle knock into the back or after when bumping; the reaction force acts of occupant waist at waist by on the stay bearing plate 61, the self-lock force that produced much larger than elastomeric element 8 of the power of Chan Shenging at this moment, waist passes through steel wire 63 by stay bearing plate 61; force transmission is arrived third connecting rod 53; excite the rotation of third connecting rod 53, drive headrest 1 by connecting rod mechanism 5 again and move forward, thus the purpose of realization protection head of passenger.The size in the hole 9 that the distance that wherein moves forward can be opened by design third connecting rod 53 middle parts be controlled, and it is 1 infinitely mobile forward to prevent from like this to rest the head on, and passenger's hindbrain is damaged.In addition, vehicle knock into the back or after bump accident after, headrest can automatically reset 1 under the effect of elastomeric element, has therefore avoided manually moving the component damage of bringing.
In concrete the enforcement, the shape in the hole 9 that open at third connecting rod 53 middle parts does not limit, the ultimate range decision that the setting of its size, shape and position can move forward according to the needs of headrest 1, because an end of the 4th connecting rod 54 is by pin that can slide in the hole 9 of third connecting rod 53 10 and third connecting rod 53 sliding block joints, the other end of the 4th connecting rod 54 is hinged with corresponding curb girder 3.The setting of size, shape and the position in the hole 9 of opening, third connecting rod 53 middle parts can limit the angle of third connecting rod 53 around corresponding curb girder 3 rotations like this, thus restriction headrest 1 distance that moves forward.The shape of third connecting rod 53 mider holes 9 of the present utility model can be waist type or strip shape.
Vehicular seats SAHR protection system of the present utility model is under normal operation; headrest 1 remains on control position; be that the waist of passenger when taking applies under the situation of certain force by stay bearing plate 61 to waist; headrest 1 can not move forward; because this moment, waist passed to the power of connecting rod mechanism 5 by stay bearing plate 61; within the self-lock force scope of elastomeric element 8, so just be not enough to start connecting rod mechanism 5 work, move forward thereby drive headrest 1.
Further, elastomeric element 8 can be preferably dependable performance, and the whirlpool spring of being convenient to install, and in-to-in one end that leans on of this whirlpool spring is fixed in the rotating shaft 7, and the exterior end that leans on of whirlpool spring is fixed on the end of first connecting rod 51.
Further, described strut bar 2 is two, and these two strut bars 2 are captiveed joint with the first connecting rod 51 of one group of connecting rod mechanism 5 by first cross bar 11, makes the motion of first connecting rod 51 can drive headrest 1 motion of captiveing joint with strut bar 2.
Further, described strut bar 2 can be made up of interior bar 21 and the outer loop bar 22 that is set on the interior bar 21, and described interior bar 21 is fixed on first cross bar 11, and outer loop bar 22 is captiveed joint with headrest 1.Under the normal operation of the utility model vehicular seats SAHR protection system, the user can move up or down thereby adjust headrest 1 by the position annexation of bar 21 in regulating with outer loop bar 22, satisfies user's comfort like this.
The utility model also provides a kind of seat with above-mentioned vehicular seats SAHR protection system.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
