Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a three-seat vehicle seat that allows the seat to rotate and change its direction while maintaining the conventional seat pitch (the distance between the seats arranged).

[0002]

[Prior art]

 Conventionally, as a three-seater seat for a vehicle, which has been devised so that it can be rotated to change its direction even under a fixed installation space, the one disclosed in Japanese Utility Model Publication No. 1-144123 is known. .

[0003]

[Problems to be solved by the device]

 However, the one disclosed in Japanese Utility Model Laid-Open No. 1-144123 is such that both outer armrests are fixed to the footrest or the inner wall side of the vehicle, respectively, and the underframe on which the cushion is placed is rotatable inside both outer armrests. Since it is attached to the outside, both outer armrests must have the same shape in the front and rear, resulting in high cost and poor appearance.

Further, it is necessary to attach components required for the reclining operation such as reclining buttons and cables provided on both outer armrests to both the front and the rear, which also raises a problem of high cost. Furthermore, since the gap between the outer armrests and the cushion is large, there is a problem that dirt or the like may occur due to the clothes being caught.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a rotary type three-seater seat for a vehicle, which does not increase the cost, has a good appearance, and does not have a risk of catching clothes or the like. It is intended.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a footrest fixed on a vehicle floor, an underframe rotatably mounted on the footrest via a rotation device, and a footframe fixed on the underframe. In a three-seater seat for a vehicle equipped with three cushions, a backrest, and both outer armrests, a front portion of the cushion is formed into a hollowed shape according to a turning radius, and rear portions of the outer armrests are formed. When the three seat cushions and the backrest and both outer armrests are rotated together with the underframe while keeping the angle at the upright of the seat back upright, It is characterized in that it does not interfere with any part of the rear seat.

[0007]

[Action]

 Since the front part of the cushion was scooped to match the turning radius, and the rear parts of both outer armrests were scooped to match the turning radius, the angle of the seat in the front seat when upright was set. Even if the three cushions, the backrest, and both outer armrests are rotated together with the underframe in this state, it does not interfere with any part of the front and rear seats.

[0008]

【Example】

 An embodiment according to the present invention will be described below with reference to the drawings. 1 is a front view of an embodiment of the present invention, FIG. 2 is a side view of an embodiment of the present invention, FIG. 3 is a plan view of an embodiment of the present invention, and FIG. 5 is a rear view of an embodiment according to the present invention, FIG. 5 is a side view of an outer armrest according to the present invention, and FIG. 6 is a side view of a conventional outer armrest.

In FIGS. 1 to 4, a leg stand 2 is fixed on a vehicle floor surface 1, and an underframe 4 is rotatably mounted on the leg stand 2 via a rotating device 3. . Then, on this underframe 4, three cushions 5, 5, 5, three backrests 6, 6, 6, two outer armrests 7, 7 and two middle armrests 8, 8 And are fixed. In the figure, 9 is a lock release pedal, 10 is a table provided on the back side of the backrest 6, and A is a human body.

The center of the front part of the three cushions 5 is slightly hollowed in accordance with the radius of gyration to form the recess 5a. Further, the outer corners of the front cushions 5 on both outer sides are also slightly scooped in accordance with the radius of gyration to form the recesses 5b. Even if these recesses 5a and 5b are formed, the comfort of sitting does not deteriorate. It is not necessary to hollow the front center of the cushions 5 on both outer sides, but in this embodiment, the recesses 5a are formed by scooping for the purpose of matching the shape of the cushion 5 in the center.

Next, the outer armrest 7 will be described. The conventional outer armrest 15 is as shown in FIG. 6, and the rear portion 15a shown by diagonal lines is an interference portion that interferes with the front seat 12 and the like when rotating. ing. Therefore, in the outer armrest 7 in the present embodiment, the rear portion which is the above-mentioned interference portion is hollowed in accordance with the radius of rotation to form the concave portion 7a as shown in FIG.

Then, in a state in which the backrest 6 of the front seat 12 is set at an upright angle (a state shown by an arrow B in FIG. 2), three cushions 5 and three backrests 6 and 2 are provided. When the seat (three-seat seat for vehicle) 13 including the outer armrests 7 and the like is rotated together with the underframe 4, the central seat 13 has a front seat 12 and a rear seat 14 of the same structure. The structure does not interfere with any part (see FIGS. 2 and 3).

Explaining the above with actual dimension values, in FIG. 3, the seat pitch a is 980 mm, which is the same as the conventional one, and when the central seat 13 is rotated in the direction of arrow E, the cushion cushion 5 rotates. The radius b is 710 mm, and the clearance d between the cushions is 15 mm. Similarly, the rotation radius e of the futon portion of the backrest 6 is 720 mm, the rotation radius f of the outer armrest 7 is 750 mm, and the clearance h between the outer armrest 7 and the back surface of the backrest 6 is 1.5 mm. The arrow F in FIG. 3 indicates the state when the central sheet 13 is rotated 90 degrees.

Further, the overall lateral width n (the sum of the three cushions 5 and the two outer armrests 7) of the vehicle three-seat seat 13 is 1470 mm, which is the same as the conventional one (see FIG. 1). The width is 40 mm. Further, the widths p, r, t of the central cushion 5 and the cushions 5 on both sides are the same as the conventional ones, and the height dimension u of the outer armrest 7 and the height dimension v of the cushion 5 are also the same as the conventional ones. Yes (see FIGS. 1 and 2). Further, the dimension w from the center of rotation to the front subordinate end of the cushion 5 and the dimension y from the front end of the cushion 5 to the front side of the backrest 6 when upright are the same as the conventional dimensions.

As described above, in the vehicle three-seater seat according to the present embodiment, even if most of the dimensions are the same as those of the conventional one, the entire three-seater seat, which has been impossible in the past, is exactly the same. It has become possible to rotate. Further, it is possible to provide a three-seater seat for a vehicle that is comfortable to sit on, does not cause a cost increase, has a good appearance, and does not have any clothes or the like caught between the outer armrests and the cushion.

[0016]

[Effect of device]

 As described above, according to the present invention, the front part of the cushion is shaped to match the turning radius, and the rear parts of both outer armrests are shaped to match the turning radius. For vehicles that do not interfere with any part of the front and rear seats even if the seat cushion and three back cushions and both outer armrests are rotated together with the underframe with the seat backrest upright angled. It can be a three-seat seat.

[0017] Furthermore, it is comfortable to sit on, does not cost much, has a good appearance, and there is a risk that dirt or the like may be generated due to the clothes or the like being caught between the outer armrests and the cushion. A seat for a vehicle that can be reliably prevented can be a three-seater seat.
