Next, operation and the beneficial effect of seat mentioned above will specifically be introduced.
In the time that occupant's upper body will move backward because being subject to the impact of the inertia producing in rear view of vehicle collision, as shown in Figure 5, chair back rack F2 is subject to coming from occupant's (not shown) load backward.Now, the Later Zhou Dynasty, one of the Five Dynasties edge 38 of chair back bogie side frame 30 is subject to coming from the load of top.When the load producing in rear impact reaches specified value when above, under the effect of the load above coming from, near the connecting portion 38A of Later Zhou Dynasty, one of the Five Dynasties edge 38 (dashed area), produce crimp, whole chair back bogie side frame 30 (chair back rack F2) swings backward.By this plastic deformation of Later Zhou Dynasty, one of the Five Dynasties edge 38, seat S can absorb the impulsive force that rear impact produces.
In addition, under the effect of the load being applied by rear impact, chair back bogie side frame 30 produces crimp at 38 places, Later Zhou Dynasty, one of the Five Dynasties edge, and, as shown in Fig. 6 (b), the border near zone that can produce between connecting portion 38A and rear portion 35A produces the such bending distortion of depression in direction inner side to the left and right with respect to the upper lateral part and the following side that are positioned at these upper and lower both sides, region.Thereby, can further absorb above-mentioned impulsive force.
In addition, even if exist by the load that collide side or similar collision produces in side direction, the border near zone that chair back bogie side frame 30 can produce between connecting portion 38A and rear portion 35A produces the such bending distortion of depression in direction inner side to the left and right with respect to the upper lateral part and the following side that are positioned at these upper and lower both sides, region.By this structure, seat S not only can absorb the impulsive force on vehicle that puts on of rearward collision generation, also can absorb the impulsive force on vehicle that puts on being produced by side collision.
In addition,, because chair back bogie side frame 30 comprises the upside protrusion 36 and the downside protrusion 37 that protrude from installation portion 35, therefore not only can, according to the mentioned above collision impact power that sponges like that, can also keep normal rigidity simultaneously.
In the present embodiment, as shown in Figure 3, because the rear portion 35A of installation portion 35 extands rearward to lagging dege 31A, therefore a part for Later Zhou Dynasty, one of the Five Dynasties edge 38 and installation portion 35 are coplanar.Like this, the structure that protrudes from installation portion 35 with whole Later Zhou Dynasty, one of the Five Dynasties edge is compared and can be reduced rigidity.By this structure, when produce impulsive force in collision time, Later Zhou Dynasty, one of the Five Dynasties edge 38 can easily produce distortion, thus impact-absorbing power effectively.
In addition, because upside protrusion 36 extends to lagging dege 31A, thereby, not only improve the rigidity of upside protrusion 36 with the load of tolerance fore-and-aft direction, and be easy to make the rear side circumference 38 that the upside protrusion 36 higher with rigidity adjoins to produce distortion.In addition, upside protrusion 36 is connected in front side with downside protrusion 37.The rigidity of front side portion that this structure has improved chair back bogie side frame 30 is the load on fore-and-aft direction with tolerance, and, make rear side rigidity be less than front side rigidity, be therefore more easy to make Later Zhou Dynasty, one of the Five Dynasties edge 38 to produce distortion.
In addition, as shown in Figure 4, clip 33, by the locational welding at border 31D upper and lower, is fixed on pipe support 20.Can realize thus so a kind of structure, in this structure, clip 33 and pipe support 20 do not interfix in the position highly identical with border 31D.Like this, be fixed on the locational structure highly identical with border 31D with clip 33 and pipe support 20 and compare, be positioned at the Later Zhou Dynasty, one of the Five Dynasties edge 38 (connecting portion 38A) of border 31D below than being easier to produce deformation.In the present embodiment, because clip 33 (the second fixed part 33B) is fixed together on the position identical with the height of connecting portion 38A bottom with pipe support 20.In the time having impulsive force input, the adjacent domain of the top of connecting portion 38A and border 31D more easily bends (more easily producing deformation).
In addition,, because the lateral inner surface of Later Zhou Dynasty, one of the Five Dynasties edge 38 and pipe support 20 are spaced apart, like this, in the time that the impulsive force producing in collision is inputted and then made Later Zhou Dynasty, one of the Five Dynasties edge 38 produce deformation, rear side periphery 38 can not get the supporting of pipe support 20 from inner side.Therefore, Later Zhou Dynasty, one of the Five Dynasties edge 38 more easily produces deformation.
In addition, as shown in Fig. 6 (a), because an angle regulator RL part is accommodated in depressed part 34, thus in the time of vehicle collision, chair back bogie side frame 30 more easily outwards produces bending distortion in angle regulator RL edge part near zone in left and right direction, and then can more effectively absorb collision impact power.
Above-mentioned impulsive force absorbing structure in the present embodiment has simple structure, wherein be positioned at Later Zhou Dynasty, one of the Five Dynasties edge 38 between upside protrusion 36 and the downside protrusion 37 of chair back bogie side frame 30 lower than these protrusions 36,37, therefore compare with existing structure, reduced the quantity of required parts.Adopt this structure in the present embodiment, can pass through stamped sheet metal or similar material, produce easily the chair back bogie side frame 30 with impulsive force absorbing structure.Can save thus labour power and the cost of manufacturing seat S.This means, can solve labour power and the Cost Problems of manufacturing seat S.
In addition, as shown in Figure 2, chair back bogie side frame 30 has the lagging dege 31B that the form of straight lines to extend along outside face 21A forms, and on this lagging dege 31B, chair back bogie side frame 30 is fixed by welding on outer surface 21A.Like this, the structure with chair back bogie side frame 30 with the encirclement forward and backward surface of pipe support 20 and the U-shaped cross section of outside face is compared, and the present invention has reduced size and the weight of chair back bogie side frame 30.The densification of chair back bogie side frame 30 can reduce the materials amount of molding, can reduce thus the manufacturing cost of manufacturing chair back bogie side frame 30.
In addition, as shown in Fig. 6 (a), because a part of angle regulator RL is accommodated in (insertion) depressed part 34, so reduced angle regulator RL outstanding degree laterally in side direction, dwindle thus the size of seat S in left and right direction.In addition, as shown in Figure 4, the main portion (that is: the rear portion 35A of connecting portion 38A and installation portion 35) of the lateral outer of Later Zhou Dynasty, one of the Five Dynasties edge 38 is positioned at the inner side of outside face 21A, the structure that is positioned at outside face 21A outside with whole lateral outer is like this compared, and the present invention has dwindled the size of seat S in left and right direction.
