Description

[Detailed Description of the Invention] The present invention relates to a rotary seat with a slider installed in an automobile or the like.

If a seat slider device that can adjust the longitudinal position of the seat is installed on a rotary seat that is conventionally installed in automobiles, the seat can be slid by operating the slide lever even while the seat is rotating. Since this is possible, the seat performs the two movements of rotation and sliding at the same time, resulting in a problem that the movement becomes unstable.

Therefore, an object of the present invention is to make it impossible to slide the seat at least while the seat is rotating, even if a seat slider device is provided on the rotary seat.

Therefore, in the present invention, a seat support member on which the seat is rotatably mounted is provided on the vehicle body, and the seat support member includes a rotation lock member for locking the rotation of the seat and a rotation lock for unlocking the rotation lock member. A rotary lock device including a release operation section and a rotation lock release transmission member that transmits the movement of the rotation lock release operation section to the rotation lock member is provided between the vehicle body and the seat support member, and the rotation lock device is provided between the vehicle body and the seat support member. A seat slider device for moving the support member in the front and back direction is provided, and
The seat support member is provided with a slide lock member that locks the movement of the seat support member at an appropriate position, a slide lock release operation unit that operates to release the lock of the slide lock member, and a slide lock release operation unit that controls the movement of the slide lock release operation unit. In a rotary seat with a slider equipped with a slide lock device comprising a slide lock release transmission member that transmits information to a lock member, there is a space between the rotation lock release transmission member and the slide lock release transmission member. This can be achieved by providing a rotary seat with a slider that is provided with a stopper member that prevents the lock release operation of the other lock release operation unit when either the operation unit or the slide lock release operation unit is operated to release the lock. It was designed to achieve the objectives of the period.

The present invention will be described below with reference to illustrative embodiments.

A is a rotary seat, which is composed of a seat cushion 11 and a seat bag 12. A cylindrical rotating shaft 14 is fixed to the center of a bottom plate 13 attached to the lower surface of the seat cushion 11. A ring-shaped rotary plate 15 having an engaging stepped portion 15a at the inner circumferential end is fixed on the same circumference of the lower surface of the bottom plate 13 with the center point 14 as the center. The rotating plate 1
At positions 180 degrees out of phase with respect to the rotary shaft 14 at both ends of the rotary plate 15, there are lock holes 1 into which the tips 28a of the latches 28 for preventing rotation of the rotary plate 15 appear and retract.
5b, 15b' are bored therein, and a latch protruding downward and formed in a substantially concave shape is provided on the same circumference on the rear side of the lock holes 15b, 15b' when viewed in the direction of rotation of the seat a. A pushing part 15c is provided in a substantially semicircular shape, and is configured to hold the latch 28 in a depressed state while the seat a is rotating, and prevent the rotation lever 27, which will be a rotation lock release member to be described later, from returning. ing. (See Fig. 3) Reference numeral b denotes a leg portion on which the seat a is rotatably placed, and the outer surface of the lower end of the leg pieces 16, 16' on both sides of the leg portion b is provided with a leg portion that is attached to the floor surface 17 of the vehicle body. bracket 18
Sliders 21, 21' are slidably fitted to fixed rails 20, 20' which are fixed parallel to each other in the front-rear direction with bolts 19, and are fixed with bolts 22 or the like. Seat slider device 23 with fixed rails 20, 20',
23' is constructed.

The upper ends of the leg pieces 16, 16' are connected at their front and rear ends by frames 24, 24',
A pair of members 25, 25' are provided in the middle between the frames 24, 24'. A rotating plate guide member 26 is fixed on the members 25, 25', and the outer peripheral edge 26a of the rotating plate guide member 26 is engaged with the engagement step 15a of the rotating plate 15. A freely fitable cylindrical support shaft (not shown) is fitted and fixed.

Also, one of the members 2
Approximately in the center of the 5' side, a latch 28, which constitutes a rotation lock device with a rotation lock release operation section and a rotation lock release transmission member, which will be described later, and serves as a rotation lock member for the seat a, is mounted via a latch holder 29. It is rotatably pivoted by a support shaft 30, and its tip 28a is connected to the lock hole 1 bored in the rotary plate 15.
5b or 15b'.

The operation of the latch 28
A substantially L-shaped hole is inserted through a through hole 16a formed in one of the leg pieces 16 at one end of the shaft 31, which is rotatably pivotally connected between the legs 6' and serves as a rotation lock release transmission member. This is done by a rotary lever 27 which is bent to form an integral rotary lock release operation section.

That is, the latch 28 of the shaft 31
A proximal end 32a of a link 32 is fitted and fixed to a portion corresponding to the latch, a proximal end 33a of a link pin 33 is fitted and fixed to a distal end 32b of the link 32, and a distal end 33b of the link pin 33 is fitted and fixed to the distal end 32b of the link 32. The latch guide 34 is loosely fitted into a long hole 34a formed in a latch guide 34 protruding from one side of the rotary lever 28.
By operating the tip 28a of the latch 28
is inserted into the lock hole 15b or 15b' to unlock the rotary plate 15.

Return springs 35 and 36 are interposed at the tip 31a of the shaft 31 and the protruding end 30a of the support shaft 30 fitted into the latch holder 29, respectively, so as to always bias the latch 28 in the locking direction. ing. In addition, the symbols 13a, 13 in the figure
A' is a lock hole drilled in the bottom plate 13 at a position overlapping with the lock holes 15b and 15b'.

A base end 37a of a link 37 is fixed to a position close to the inside of one of the leg pieces 16 of the shaft 31, and a stopper piece serving as a stopper member on the rotary lock device side is attached to the tip of the link 37. 3
8 is bent toward the one leg 16 side and formed integrally.

A plurality of lock holes 39 are drilled in the side surface of the fixed rail 20 at appropriate intervals in the front-rear direction, and a tip 40a of a lock pin 40 serving as a slide lock member provided on the back surface of the one leg piece 16 is provided. It is designed to haunt you.

The lock pin 40 is a component that constitutes a slide lock device with a slide lock release operation section and a slide lock release transmission member, which will be described later.
It is attached to the back surface of the one leg piece 16 via a bracket 41 so as to be slidable in the left-right direction, and its tip 40a has a through hole (not shown) drilled in the one leg piece 16 and the slider 21. A plurality of lock holes 39 are drilled through the fixed rail 20.
It is made to appear in one of the following.

The locking pin 40 is disposed parallel to the inner side of the one leg 16 and is operated by the rear end 4.
The front end of the shaft 42, which serves as a slide lock release transmission member rotatably pivoted to the mounting member 43 fixed on the bracket 41, is bent into a substantially L-shape. This is performed by a slide lever 44 which is a slide lock release operation section formed therein.

That is, the upper end 45a of the link 45 is fixed to the portion below the rear end 42a of the shaft 42 where the lock pin 40 is located, and the lower end 45b of the link 45 is fixed.
is loosely fitted into an engagement hole 40b formed in the lock pin 40 through the bracket 41, and by operating the slide lever 44, the tip 40a of the lock pin 40 is inserted into the lock hole 39. and seat slider device 23,
23', and a return spring 46 is interposed near the rear end 42a of the shaft 42, which normally urges the lock pin 40 in a direction to push out the seat slider. It is adapted to lock the devices 23, 23'.

A position where the shaft 42 three-dimensionally intersects with the shaft 31 having the rotary lever 27 (the shaft 42 is set to be below the shaft 31 having the rotary lever 27).
A stopper piece 47 serving as a stopper member on the slide lock device side is fixed to the inside thereof.

The stopper piece 47 and the stopper piece 38 on the rotary lock device side form a lock release operation blocking portion, and when the two come into contact, either the rotary lever 27 or the slide lever 44 is activated. When operated, the lock release operation of the other lever is stopped.

Now, when rotating the seat a, when the rotation lever 27 is rotated in the X direction, the link 37 is also rotated in the X' direction, and the lower end 38a of the stopper piece 38 on the rotation lock device side is locked into the slide lock. Since it comes into contact with the upper surface 47a of the stopper piece 47 on the device side, the slide lever 44 cannot be operated.

Therefore, since the seat slider device 23 cannot be unlocked while the seat a is rotating, the seat a rotates stably without sliding. (See Figures 4 to 6) Also, when sliding sheet a,
When the slide lever 44 is rotated upward (in the Y direction), the stopper piece 47 on the slide lock device side fixed to the shaft 42 also rotates in the Y' direction. Even if you try to operate the lever 27, the side surface 38b of the stopper piece 38 on the rotary lock device side joins the side surface 47b of the stopper piece 47 on the slide lock device side (see FIGS. 7 and 8), so it must be rotated completely. I can't.

Therefore, since the rotation lock device cannot be released while the seat a is sliding, the seat a does not rotate.

In the above embodiment, when the rotary lever 27 is operated, the slide lever 44 is held down so that it cannot be operated, and when the slide lever 44 is operated, the rotary lever 27 is disabled, but the present invention is not limited to this. Instead, only one of the two operations may be used.

Further, in the above embodiments, the seat back is of a fixed type, but the device can also be applied to a rotating seat equipped with a seat back folding mechanism or a reclining device equipped with a seat bag folding mechanism.

As described above, according to the present invention, the rotation of the slide lever is prevented while the seat is rotating, and the rotation of the rotation lever is prevented while the seat is sliding, so that the rotation of the seat is prevented. Inside, the center of rotation of the seat does not move and rotates stably. Therefore, not only can the seat be rotated easily, but also the seat can be rotated smoothly without fluctuation or wobbling, thereby further improving safety. Furthermore, even if the slide lock device accidentally comes into contact with the slide lever during rotation, the slide lock device will not come off, so erroneous operations can be prevented.
