Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating stool to be mounted on various vehicles such as a railway vehicle, an automobile, an aircraft or a ship (hereinafter referred to as “vehicles”), and particularly, a wide vehicle stool for three persons is rotated in the front and rear directions. The present invention relates to a rotating stool for a vehicle, which is made possible.

[0002]

[Prior art]

 Conventionally used rotating stools for vehicles are equipped with an underframe via a rotating device on a foot stand fixed to the floor of the vehicle, and armrests, seat cushions, backrests, and tables are attached to the underframe. Thus, the stool body is configured, and the stool body is rotated together with the underframe so that the seat can be turned in the front-back direction.

[0003]

[Problems to be solved by the device]

 However, even in the above-mentioned rotating stool, many stools for two persons are often used. However, for a vehicle stool having a laterally wide width such as three persons, as shown in FIG. 7, as shown in FIG. Since the armrests 52 on both sides interfere with the tip portion 53a of the seat cushion 53 of the other stool A during rotation, the direction of the seat could not be rotated forward or backward.

If it is attempted to rotate the vehicle seat for three persons, it is necessary to set the seat pitch and the like based on the turning radius of the seat body 51, and therefore only the protrusion of the tip portion 53a of the sitting seat 53 is required. In addition, the dimension W from the center of rotation X to the back of the backrest 54 cannot be made large, and the sitting space on the floor of the vehicle is formed by the outermost part of the seat including the rotation trajectory of the armrest 52. It required a wide range that would not be interfered by other seats A with the turning radius placed in front of and behind it, and the inner wall of the vehicle. Therefore, not only the lateral width of the stool body 51 but also the front and rear width of each seat troupe 53 is shortened to prevent interference with the seat hood 53 and the backrest 54 of other stools A located in the front and rear. There was a problem that the area became extremely narrow and a feeling of pressure was generated, and passengers could not sit in a rotating stool in a comfortable posture.

Further, since the armrest of the vehicle stool is a necessary element for the stool that has important functions such as buttons for reclining operation, switches for lighting lamps, and ashtray, the armrest can be rotated by removing the armrest. The rotation locus of the stool could not be reduced.

The present invention was devised in view of the above problems, and even in a laterally wide vehicle stool for three people, the sleeves of the armrests on both sides of the stool are placed at the bottom of the seat hood. It is constructed in a special shape that bites into it, and it is rotated without narrowing the width of each seat so that the sleeves of the armrests on both sides do not interfere with the tips of the seat buns of other stools located in front and behind. An object of the present invention is to provide a rotating stool for a vehicle that can perform the following.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, a rotary seat for a vehicle according to the present invention rotatably mounts an underframe on a pedestal via a rotating device, and places the underframe at an appropriate position on the pedestal. In a rotating seat that constitutes a rotation stop device that is fixed to a use position in a fixed direction and that enables the turning motion of the underframe by releasing the rotation stop device, lower the sleeve body that is fixed on both sides of the underframe. The gist is that the outer surface of the lower part of each sleeve body is bent toward the center of rotation so that the outer surface of the lower part of the sleeve fits within a rotation locus that does not interfere with the tips of seat cushions of other front and rear rotary seats when the rotary seat is rotated. It is a thing.

The sleeve body has a base portion whose side surface has an arc shape so that the sleeve body can be fixed along a side surface of the underframe formed with an arc shape, and a rising portion which rises upward at a rear end of the base portion. A mounting portion for mounting an armrest on the upper portion of the rising portion so as to be positioned outside the rotation locus.

[0009]

[Action]

 According to the above configuration, when the stool is rotated, the lower part of the sleeve body on both sides of the stool is bent toward the center of rotation, so that the sleeve body interferes with the tip of the seat hood of another front and rear rotary stool. Since the vehicle can be rotated without rotating, even a wide vehicle stool for three persons can be rotated in the front-rear direction without reducing the width of each seat. Further, since the armrest is fixed on such a sleeve, various functions such as buttons for reclining operation built in the armrest are not impaired.

[0010]

【Example】

 Hereinafter, an embodiment of a rotary seat for a vehicle according to the present invention will be described with reference to the drawings. 1 and 2 show the whole of a rotary seat for a vehicle for three persons according to the present invention, in which reference numeral 1 is a footrest fixed to a floor surface of a vehicle or the like. The underframe 3 is attached via the rotating device 2, three seat hoods 4, 4, 4 are placed in parallel on the underframe 3, and a reclining device is provided at the rear end of the seat buns 4, 4, 4. (Not shown), the backrests 5, 5 and 5 are erected upright rearward, and the sleeves 6 and 6 are fixed to the side positions of the seat cushions 4 and 4 on both sides, and the sleeves 6 and 6 are fixed. A stool body 8 is constructed by mounting armrests 7, 7 on top of each. The rotary stool constructed in this way is used by rotating the stool main body 8 together with the underframe 3 in the front-rear direction, and a rotation stopping device (not shown) is provided between the pedestal 1 and the underframe 3. No.) is mounted, the stool body 8 is fixed to a use position in a predetermined direction by the rotation stopper device, and the rotation stopper device can be released by the pedal 9.

3 and 4 (a), (b), and (c) show a sleeve body portion according to the present invention, and the sleeve body 6 has a lower portion formed into a side surface shape of the seat cushion 4 on both sides. A sleeve body base portion 6a fixed to a side surface position of the seat pad 4, that is, a side surface of an underframe 3 described later, and a rear portion of the sleeve body base portion 6a are formed in a circular arc shape (see FIGS. 4A and 4C). That is, the sleeve body rising portion 6b is formed on the backrest 5 side, and the mounting portion 6c for mounting the armrest 7 on the upper end portion of the sleeve body rising portion 6b. The outer surfaces of the seat cushions 4 and 4 on both sides of the stool body 8 are formed in the same circular arc shape as the rotation locus around the center point X of rotation of the stool body 8 (see FIG. 6). Are fixed to the both ends of the underframe 3 having an arc shape similar to the side shape of the above, by screwing into the screw holes 10, 10 ... Transmitted through the sleeve body base 6a. As if the lower part of the sleeve body 6 was installed so as to bite into the lower part of the side face of the seat hood 4, the sleeve body rising portion 6b is formed so as to bend toward the center of rotation at the rear end portion of the sleeve body base 6a. Therefore, when the stool is rotated, it does not interfere with the front end portion 4a of the seat cushion 4 of the front and rear rotating stools. On the other hand, the armrest 7 is attached at a height position where it does not interfere with the front end portion 4a of the seat cushion 4 of the front and rear rotary stools. However, since the armrest 7 is placed on the sleeve body attaching portion 6c of the sleeve body 6 having the special shape as described above, the space between the armrests 7 and 7 is not narrowed. It should be noted that although it does not interfere with the front end 4a of the seat hood 4 of the front and rear rotary stools, it is necessary to avoid interference with the backrest 5 and the wall surface of the front and rear rotary stools. As shown in the plan view, it is formed in an arc shape.

The mounting position of the rotating device 2 of the rotary seat according to the present invention to the underframe 3 is slightly shifted to the backrest 5 side as compared with the conventional rotary seat. That is, the rotation center point X is shifted rearward, and the tip portion 4a of the seat cushion 4 is slightly projected. This projection is a portion formed so as to bend in the direction of the rotation center point X of the sleeve body 6 described above. It is configured to absorb the collision during rotation.

5 and 6 show a state in which the rotary stool according to the present invention is rotated. When the stool body 8 is rotated in the front-rear direction, it is similar to the conventional rotary stool for two persons. Then, by depressing the pedal 9 to release the anti-rotation device and rotating the stool body 8 in a desired direction, the turning operation of the rotary stool can be completed. At this time, when the stool body 8 is rotated 90 degrees, both side faces of the seat cushions 4 and 4 on both sides of the stool body 8 are arc-shaped, and the tips of the seat cushions 4 of the other rotating stools located in the front and rear are formed. It does not interfere with the back surface of the portion 4a or the other backrest 5 of the rotary seat.

In the above description, the rotary stool for three-seater was described, but the rotary stool for which the front-rear distance must be shortened due to installation in the vehicle is not limited to three-seater. Needless to say, the structure of the rotary stool according to the present invention can be implemented even for the rotary stool for two or four persons.

[0015]

[Effect of device]

 Since the rotary stool for a vehicle according to the present invention is configured as described above, when the stool is rotated, the lower parts of the sleeves on which the armrests on both sides of the stool to be rotated are placed are bent toward the center of rotation. Since the sleeve body is configured so as not to interfere with the tip of the seat hood of the other front and rear rotating stools, it is possible for three-seater vehicles with a wide lateral width, which was impossible in the past. It has the characteristics that even a rotating stool can be rotated in the front-rear direction, the passengers can sit on the rotating stool in a comfortable posture without reducing the width of each seat. The practical effect after implementing the present invention is extremely large.
