The vehicle body 12 includes: left and right side plates 15 partitioning a door opening 14 accommodating the side door 13; and a roof 16 connecting upper ends of the left and right side panels 15 to each other. Rear bumpers (rear bumpers) 17 are joined to the left and right side plates 15 from the rear. The rear bumper 17 connects the left and right side plates 15 to each other. The side plate 15 includes an outer plate (outer panel) 15a that contributes to the aesthetic appearance by being painted on the outer surface.

In the roof 16, a rear door 18 is supported swingably about a horizontal axis. A door opening 19 for accommodating a rear door 18 is defined in the vehicle body 12 above the rear bumper 17. The door opening 19 is opened and closed by the rear door 18.

As shown in fig. 2, the vehicle body 12 further includes: a damper cover 21 rigidly coupled to the side inner plate 15b and supporting a damper (not shown) of the rear wheel; and a damper reinforcement 22 rigidly coupled to the side inner panel 15b and extending upward from the damper housing 21. The side inner panel 15b is covered with the outer panel 15a from the outside, and forms the side panel 15 in cooperation with the outer panel 15a. The damper reinforcement 22 includes a hollow body 22a, and a closed cross section is formed between the hollow body 22a and the side inner panel 15b. A rear pillar 23 is coupled to each side plate 15, and the rear pillar 23 partitions the left and right edge portions of the door opening 19 opened and closed by the rear door 18. The side plate 15 extends forward from the rear pillar 23. The damper reinforcement 22 is disposed apart from the rear pillar 23 by a distance Ds, for example.

As shown in fig. 3, the vehicle body 12 further includes a cross member 24, and the cross member 24 connects upper ends of the left and right rear pillars 23 to each other and supports the roof 16 from below. The cross beam 24 separates the upper end of the door opening 19.

The rear pillar 23 includes a pillar inner portion 23a, and the pillar inner portion 23a is rigidly joined to the inner surface of the side inner panel 15b. For example, welding may be used for the joining. The column inner 23a is connected at an upper end to a side end of the cross member 24. The column inner portion 23a has: a front wall 26a rising inward from a welded portion 25 overlapping the inner surface of the side inner panel; and an inner wall 26b extending rearward from an inner end of the front wall 26 a. Above the absorber reinforcement 22, a retractor bracket 27 supporting a seatbelt retractor is joined to the column interior 23 a. Above the retractor bracket 27, the webbing anchor 28 is fixed to the side inner panel 15b. The seatbelt retractor is used to adjust the length of a seatbelt tied to an occupant. The belt anchor 28 is used to secure the shoulder strap of the belt to the rear post 23.

As shown in fig. 4, the rear pillar 23 includes a pillar outer portion 23b joined to a pillar inner portion 23a from the outside. As shown in fig. 5, the column inner 23a and the column outer 23b cooperate to form a closed section. The column outer portion 23b includes: a rear wall 29a engaged with the outer surface of the column inner 23a at an inner edge and extending outwardly from the outer surface of the column inner 23 a; a side wall 29b extending forward from an upper end of the rear wall 29 a; and a front wall 29c that extends continuously from the front end of the side wall 29b toward the side inner panel 15b, is laminated at the welding portion 25 of the pillar interior 23a at the welding portion 31, and sandwiches the side inner panel 15b with the welding portion 25. The welded portion 25 of the pillar inner portion 23a, the rear edge of the side inner panel 15b, and the welded portion 31 of the pillar outer portion 23b are laminated in this order and rigidly joined. For example, welding may be used for the joining.

An extension flange 32 is formed at the position of the webbing anchor 28 on the column outer portion 23b, and the extension flange 32 extends to a position forward of the column inner portion 23 a. The extension flange 32 may be formed from a continuous sheet of material from the weld 31. The extension flange 32 overlaps the outer surface of the side inner panel 15b. An anchor plate 33 for supporting the belt anchor 28 is overlapped on the extension flange 32. The extension flange 32 overlaps the anchor plate 33 from the inside and supports the anchor plate 33 from the inside. Thus, anchor plate 33 is engaged to rear post 23.

Here, the side inner panel 15b, the extension flange 32, and the anchor plate 33 overlap and are joined to each other at the first joining region 34. The first bonding region 34 is constituted by, for example, a welding point (welding trace). The first engagement region 34 is arranged along the periphery of the anchor plate 33. Here, four points are set along the periphery. The extension flange 32 is expanded to a first engagement area 34a provided at the front end of the anchor plate 33. The side inner panel 15b includes a convex structure 35 that bulges toward the vehicle outside as approaching the first joining region 34.

The welding portion 31 of the pillar outer 23b is joined to the outer surface of the side inner panel 15b at a second joining region 36. The second bonding region 36 is constituted by, for example, a welding point (welding trace). As shown in fig. 3, at the second joining region 36, the rear end of the side inner panel 15b is joined to the pillar inner 23 a. In this way, the rear end of the side inner panel 15b is sandwiched and joined between the pillar inner 23a and the pillar outer 23b at the second joining region 36.

As shown in fig. 6, the retractor bracket 27 is engaged with the column interior 23 a. Comprising a plurality of mounting

tabs

37a, 37b, 37c, 37d. At least one of the mounting tabs 37a overlaps and is rigidly joined to the post exterior 23b and post interior 23 a. For example, welding may be used for the joining.

The pillar inner 23a has a protruding portion 39, which protruding portion 39 protrudes forward of the vehicle body at the height of the anchor plate 28, and engages with the side inner panel 15b at the third engagement region 38. The protruding portion 39 may be continuously bent from the plate material of the column inner portion 23a from the welding portion 25. The third joint region 38 is constituted by, for example, a welding point (welding trace).

When a large load acts on the occupant to which the seat belt is fastened in the forward direction, the load is transmitted from the shoulder belt to the seat belt anchor 28. At this time, the rear pillar 23 can satisfactorily support the tensile load acting on the webbing anchor 28 by the closing cross-section. That is, the toppling of the anchor plate 33 can be suppressed. Since the support for the webbing anchor 28 is released from the absorber reinforcement 22, the degree of freedom in design of the absorber reinforcement 22 can be expanded. Ride comfort can be well adjusted.

In the vehicle body 12 of the present embodiment, the side inner panel 15b, the extension flange 32, and the anchor plate 33 overlap and are joined to each other at the first joining region 34. Since the three members overlap and are joined, the support strength of the seat belt can be sufficiently ensured based on the increase in the total plate thickness. Further, since the first engagement region 34 is disposed along the peripheral edge of the anchor plate 33, the closed cross section of the rear pillar 23 can be utilized more efficiently via the pillar outer 23b when supporting the tensile load applied by the webbing anchor 28. Pouring of anchorage plate 28 can be well inhibited.

In the present embodiment, the extension flange 32 is expanded to a first engagement area 34a provided at the front end of the anchor plate 33. As a result, the closed cross section of the rear pillar 23 can be more effectively utilized via the pillar outer 23b when supporting the tensile load applied by the webbing anchor 28. Pouring of anchorage plate 28 can be well inhibited.

The rear end of the side inner panel 15b is joined between the pillar inner 23a and the pillar outer 23b at the second joining region 36. The strength of the support of the seat belt by the second engagement region 36 can be further improved.

The pillar inner 23a of the present embodiment has a protruding portion 39, which protruding portion 39 protrudes forward of the vehicle body at the height of the anchor plate 33, and is joined to the side inner panel 15b at a third joining region 38. Since the post interior 23a engages the side panel 15 at the location of the anchor plate 33, the closed profile of the rear post 23 can be utilized more efficiently in supporting the tensile load applied by the seat belt anchor 28. The toppling of the anchor plate 33 can be well suppressed.

In the present embodiment, the side inner panel 15b includes a convex structure 35 that bulges toward the vehicle outside as approaching the first joining region 34. Since the side inner panels 15b support the anchor plate 33 in the convex configuration 35, the side panels 15 may help support the tensile load applied by the seat belt anchor 28. The support strength of the seat belt can be further improved.

The retractor bracket 27 has a mounting piece 37a that overlaps and engages the column outer portion 23b and the column inner portion 23 a. By overlapping and joining the mounting piece 37a of the retractor bracket 27 with the column inner portion 23a and the column outer portion 23b, the support rigidity of the seatbelt retractor can be ensured.

In the vehicle body 12 of the present embodiment, the damper reinforcement 22 is disposed separately from the rear pillar 23. Since the rear pillar 23 is separated from the damper reinforcement 22 in this way, the strength of the damper reinforcement 22 can be freely set, and as a result, the push-up rigidity from the damper can be relaxed. The push-up rigidity can be adjusted to be optimal. Adjustment of the push-up rigidity can contribute to improvement of riding comfort. In this way, the support strength of the belt anchor 28 can be ensured while adjusting the push-up rigidity. At this time, the damper reinforcement 22 includes the hollow body 22a, and a closed cross section is formed between the hollow body 22a and the side inner panel 15b, so the damper reinforcement 22 can contribute to reinforcement of the push-up rigidity.
