[0116] Figure 7 and Figure 8 The second embodiment of the present invention is shown, and differs from the first embodiment described above in that the structure of the fixed support frame 19 is different. And, with Figure 1 to Figure 4 The same symbols are used for the same parts and their detailed descriptions are omitted.

[0117] Such as Figure 7 As shown, two screw holes (not shown in the figure) are provided on the cross bar member 13 on the inner side in the vehicle width direction than the extended part 16 of the bumper member 15, and on these screw holes, bolts 50 are fixed. A loudspeaker mounting support frame 25 which is approximately in the shape of a rectangular plate as a support member. On the reverse side of this speaker mounting bracket 25, a speaker 26 as a vehicle-mounted device is mounted.

[0118] The vehicle width direction outer lower end portion of the above-mentioned loudspeaker mounting support frame 25 is also fixed by bolts 50 in the vehicl...

Embodiment approach 3

[0139] figure 2 , represents the side body structure 2 on the rear side of the right side vehicle seat (not shown) in the convertible. This side vehicle body structure 2 includes: a front rib portion 3 extending in the front-rear direction of the vehicle body, an upwardly bent portion 5 extending obliquely from the front rib portion 3 to the rear side of the vehicle body, and a rear rib portion 5 extending rearwardly. Rib portion 7, and left and right side panels 9. Also, if Figure 12 As shown, a horizontal frame 6 extending in the vehicle width direction is provided behind the upwardly bent portion 5 .

[0140] Such as Figure 13 As shown, the above-mentioned upward bending part 5 has its upper end bent backward, and the front side horizontal part of the "L" shaped part is welded on the back near its upper end, and the rear side extending upward from the horizontal part The upper end of the vertical part is welded to the front end side of the rear rib part 7 welded to the...

Abstract

To effectively absorb a side collision load by transmitting the load applied to a side panel 9 to a cross member 6 in a side vehicle body structure 1 of a vehicle.

Description

technical field [0001] The present invention relates to a vehicle bumper structure. Background technique [0002] Hitherto, convertible cars have been provided with vehicle safety components extending in the up-down direction of the car body in order to protect the head of the occupant when the car rolls over. In order to increase the strength of this vehicle safety member, it is known to combine the vehicle safety member with a reinforcing member (connection member) extending in the vehicle width direction. [0003] For example, in Patent Document 1, a connecting member extending in the vehicle width direction is fixed on a bracket (Bracket) for supporting the hood fixed on a side panel (Sid Panel), and the connecting member is fixedly supported by a plate. It is also known that the frame encloses the vehicle insurance component, and then links the vehicle insurance component and the side plate by the connecting component. [0004] By connecting the vehicle insurance comp...
