By main with reference to the state of Fig. 6 and 7 explanation vehicle body rear part structure 100 when colliding etc. Fig. 7 is the figure illustrating the example that vehicle body is out of shape when colliding. Noting, Fig. 7 is the figure produced based on simulation, and the reason in order to illustrate exaggerates the distortion of vehicle body. (a) of Fig. 7 illustrates the state of the vehicle body rear part structure 100 of this enforcement mode, and (b) of Fig. 7 illustrates the state of comparative example vehicle body rear part structure 200. (b) of (a) of Fig. 7 and Fig. 7 schematically shows the vehicle body rear part structure 100 and vehicle body rear part structure 200 observed from rear. (b) of (a) of Fig. 7 and Fig. 7 also illustrates frame (frame) 116a, 118a, 216a and the 218a in the corresponding vehicle seat pillow being connected to seat backrest 116,118,216 and 218.
Fig. 1 is seen when the weight of the occupant being sitting on back seat 108 is applied to such as seat securing band 130a(when colliding etc.) time, the load obliquely represented with arrow B in figure 6 is applied to hinge 120 and the first fixer 110a especially. Crossbeam 140 and rear floor 106 by this load to pull-up, consequently, it is possible to be deformed into arc upwards (convex) shape.
For solving this problem, as shown in (a) of Fig. 7, in vehicle body rear part structure 100, two ends of crossbeam 140 and be positioned at the part near the middle part of vehicle and be connected to frame component 144 via support 146a, 146b and 146c. If crossbeam 140 is about to be deformed into arc, then stress is applied to frame component 144 via support 146a, 146b and 146c. As mentioned above, it is necessary, frame component 144 structure that to be rigidity higher than the rigidity on rear floor 106 and crossbeam 140, therefore stress resisted by frame component 144. Result, it is possible to suppress the distortion of vehicle body, namely can suppress the distortion of rear floor 106 and crossbeam 140.
Especially, distortion (skew) degree of crossbeam 140 maximum, part near middle part be connected to frame component 144 via support 146c, thus can more effectively suppress the distortion of rear floor 106 and crossbeam 140. Thus, in vehicle body rear part structure 100, the power being applied to crossbeam 140 via rear floor 106 from hinge 120 or the first fixer 110a is also born by frame component 144.Noting, the power being applied to crossbeam 140 due to the reason of the 2nd fixer 112a is such as born by frame component 144 via support 146a. The power being applied to crossbeam due to the reason of other the first fixer 110b, 110c and other the 2nd fixer 112b is such as also born by frame component 144 via support 146b, 146c. Therefore, in vehicle body rear part structure 100, it is possible to suppress the distortion of vehicle body when colliding.
On the other hand, as shown in (b) of Fig. 7, comparative example vehicle body rear part structure 200 is with the difference of vehicle body rear part structure 100: vehicle body rear part structure 200 does not comprise frame component 144. In vehicle body rear part structure 200, the power caused by first fixer 110a, 110b and 110c, the 2nd fixer 112a and 112b and hinge 120 self is born by rear floor 206 and crossbeam 240.
