(44) Returning to
(45) The vehicle 10 further includes a transfer mechanism 286 that transmits movements of the steering wheel 28 to the pair of front wheels 16. The transfer mechanism 286 is preferably any appropriate conventional rack and pinion type transfer mechanism, for example.
(46) According to the vehicle 10 described above, the frame portion 20 and the roll-over protection cage 22 are connected by the pair of support portions 90a, 90b that extend in the up-down direction and are connected to each other by the cross member 92. This makes it possible to improve the rigidity of the vehicle 10 as a whole and to securely fix the cross member 92 in the vehicle 10 even if the vehicle 10 is increased in size in the fore-aft direction by including the front row 12 and the rear row 14 arranged in the fore-aft direction. In addition, the cross member 92 that is securely fixed to the vehicle 10 is located between an upper end of the shoulder anchor 220 and a lower end of the winding device 218 in the front view. Therefore, it is possible to dispose both of the shoulder anchor 220 and the winding device 218 adjacent the cross member 92, and to securely support the shoulder anchor 220 and the winding device 218 by the cross member 92. The cross member 92 extends in the width direction of the vehicle 10 between the front row 12 and the rear row 14, while the cross member 92 connects the pair of support portions 90a, 90b to each other at positions higher than their centers, in the up-down direction, of the pair of support portions 90a, 90b. This makes it possible to dispose the cross member 92 sufficiently above the seat surfaces (upper surfaces of the seat bottom portions 172, 176, 180) of the seat portions 166, 168, 170 in the rear row 14. As a result, it is also possible to dispose the winding device 218, which is located at a position lower than the cross member 92, sufficiently above the seat surfaces (upper surfaces of the seat bottom portions 172, 176, 180) of the seat portions 166, 168, 170 in the rear row 14. In other words, neither of the cross member 92 and the winding device 218 is disposed at a position lower than the knees of the passengers sitting in the rear row 14, and the arrangement ensures passenger comfort in the rear row 14 (see
(47) Each of the first support portion 108 and the second support portion 110 is securely connected to the cross member 92 at two locations, i.e., at both end portions thereof. Also, each of the first support portion 108 and the second support portion 110 is preferably U-shaped or substantially U-shaped. This makes it possible to attach the shoulder anchor 220 to the first support portion 108 so as not to protrude outward beyond an outer perimeter of the first support portion 108, and to attach the winding device 218 to the second support portion 110 so as not to protrude outward beyond an outer perimeter of the second support portion 110. Therefore, it is possible to protect the shoulder anchor 220 and the winding device 218.
(48) Each of the grab bars 116, 118 includes one end portion attached to the cross member 92. This fixes the position of these end portions of the grab bars 116, 118, preventing the grab bars 116, 118 from protruding in the width direction of the vehicle 10. The grab bars 116, 118 include other end portions attached to the second support portion 110. This arrangement mutually enhances the connection strength of the grab bars 116, 118 and the second support portion 110 to the cross member 92.
(49) Since the support portions 90a, 90b and the cross member 92 are connected by the fasteners 101, it is easy to remove the cross member 92 from the support portions 90a, 90b when the vehicle 10 is to be transported. This makes transportation of the vehicle 10 easy.
(50) The seat portion 138 includes the headrest portion 160, and the cross member 92 overlaps the headrest portion 160 in the front view. Therefore, it becomes possible to easily support the headrest portion 160 of the seat portion 138 in the front row 12 by the cross member 92.
(51) In the width direction of the vehicle 10, the shoulder anchor 220 and the winding device 218 are located adjacent the seat portion 136. In other words, the shoulder anchor 220 and the winding device 218 are located on a side closer to the seat portion 136 when viewed from the seat portion 138. Therefore, this arrangement sufficiently reduces sway of the passenger sitting in the seat portion 138 toward the seat portion 136. Thus, the driver drives the vehicle 10 more comfortably.
(52) In the preferred embodiments described above, description was made for a case where the seat unit 24 preferably includes a plurality of seat portions 136, 138, 140 that are individual components from each other, and the seat unit 26 includes a plurality of seat portions 166, 168, 170 that are individual components from each other, for example. However, the seat unit may include a plurality of seat portions that are integral with each other. Therefore, preferred embodiments of the present invention are also applicable to vehicles that include bench seats.
(53) In the preferred embodiments described above, description was made for a case where the seat back portion and the headrest portion are separate from each other and defined by individual elements. However, the seat back portion and the headrest portion may be integral with each other.
(54) In the preferred embodiments described above, description was made for a case where the seat unit 24 preferably includes three seat portions 136, 138, 140, and the seat unit 26 includes three seat portions 166, 168, 170.
