Abstract

PROBLEM TO BE SOLVED: To form a reclining handle compact, and improve operability by linking a pushbutton type reclining handle to be embedded on the tip side of an arm rest through a push-pulle cable to a release lever facing a free lock adjuster. SOLUTION: As a pushbutton 38 of a reclining handle 23 is pushed, a bell crank 33 is oscillated, move of the bell crank 33 is transmitted through a push- pull cable 24 to a release lever 22, and a free lock adjuster 21 is released through a push rod 27. A seat back 12 is adjusted to a proper angle, and the pushbutton 38 is returned, so the push rod 27 is released from the release lever 22 to fix the free lock adjuster 21. The seat back 12 is thus fixed to a seat cushion 11 to be stepplessly angle-adjustable.

DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, the reclining seat of the present invention will be described based on the specified and illustrated specific examples. FIGS. 1 to 5 show the present invention embodied as a passenger seat. Partly showing a specific example 10 of the reclining seat of
Then, a free lock adjuster 21 is arranged between the seat cushion 11 and the seat back 12 so that the seat back 12 can be fixed to the seat cushion 11 steplessly at an appropriate expansion / contraction position, Also,
The release lever 22 faces the push rod 27 of the free lock adjuster 21, and the seat
The push rod 27 placed on the cushion 11
, A push button type reclining handle 23 is embedded in the distal end side of the armrest 15, and a push pull cable 24 is further attached.
One end is connected to the reclining handle 23 and the other end is connected to the release lever 22, so that the reclining handle 23 can operate the release lever 22.

The free lock adjuster 21 is
Gas free lock cylinder and its seat cushion 11 comprises a bracket 18 at the front end of the seat cushion frame 13, while its seat back 12 hinges an arm 17 to a seat back frame 14. Since it extends downward from the center, the head of the cylinder 25 is swingably connected to the tip of its arm 17, and the tip of the piston rod 26 is fixedly supported by the angle flange 19 of its bracket 18. And is arranged between the seat cushion 11 and the seat back 12.

The release lever 22 has the free lock adjuster 21 and the push rod 27.
Is fitted to the piston rod 26 so that it can be inserted into and removed from the piston rod 26, so that it is swingably supported by the bracket 18 so as to face the tip of the push rod 27, and
It is rocked and pushes its push rod 27. As such, this release lever 22 acts as a push plate and unlocks and locks its free lock adjuster 21.

The reclining handle 23 has a button housing 29 at one end and a cable retaining flange 30 at the other end, and is fixedly incorporated in the armrest 15.
The body 28 has a pin flanger 36 at one end and one end of the push-pull cable 24 is connected at the other end, and the pin plunger 36 is attached to the button
A bell crank 33 pivotably supported by a pin 37 on the handle body 28 between the button housing 29 and a cable retaining flange 30 so as to fit in the housing 29, and an armrest 15 thereof.
A push button 38 that is pushed out to fit into the button housing 29 and pushes the pin plunger 36, and a cap 39 that holds the push button 38 in the button housing 29 in a disengaged state. It can be assembled with.

More specifically, the handle,
The body 28 is provided with a slot-shaped slot 31 extending from the button housing 29 toward the cable retaining flange 30 side, and a ring-shaped groove 48 is formed on the outer peripheral surface of the button housing 29 to form the ring shape. A U-shaped handle bracket 49 is engaged with the groove 48, and is screwed to the frame 16 of the armrest 15 by the U-shaped handle bracket 49.
Of course, the U-shaped handle bracket 49 is a combination of the main bracket 50 and the sub-bracket 51 as shown in FIG.

The bell crank 33 has a long arm 3
The pin plunger 36 is integrally provided at the tip of the pin 4, the long arm 34 is fitted into the slot-like slot 31, and the pin 37 is swingably supported by the handle body 28. The bell crank 33 then connects one end of the push-pull cable 24 to the tip of the short arm 35, and the pin 3
It is swung around 7 to push and pull its push-pull cable 24.

The cap 39 is made in a structure having a decorative flange 41 at one end of a nipple 40, and is fitted into the button housing 29 of the handle body 28, and a ring groove 42 is formed into a ring shape of the button housing 29. The clip 43 is fitted to the slot 32, and the clip 43 is fitted into the ring-shaped slot 32 and the ring groove 42 so that the clip 43 is prevented from coming off from the button housing 29. Further, the cap 39 prevents the push button 38 from coming off with the decorative flange 41.

The push-pull cable 24 is made up of an outer cable 44 and an inner cable 45 that is slidably fitted in the outer cable 44, and the outer cable 44 has one end. A cable guide connector 46 on the cable retaining flange 30 of the handle body 28,
The other end is fixedly fixed to the clamp plate 20 of the bracket 18 by a cable connector 47,
The inner cable 45 is fixed to the tip of the short arm 35 of the bell crank 33 at one end and to the tip of the release lever 22 at the other end, and the reclining handle 23 is used to release the release lever 22.
Can be operated.

As mentioned above, the reclining
Since the handle 23 has a structure in which the push button 38 is operated, the handle 23 is downsized and can be embedded in the tip side of the armrest 15, and the push button 38 is slightly depressed by a pad. Since the armrest 15 is projected to the inner surface of the armrest 15, the clothes are prevented from being caught by the push button 38. As such, the reclining handle 23 can be arranged on the distal end side of the armrest 15 without being restricted by the installation location, and the operation becomes easy.

Further, in this passenger seat 10,
The push button 38 is pressed to swing the bell crank 33, and the movement of the bell crank 33 is transmitted to the release lever 22 via the inner cable 45 of the push-pull cable 24, and the release lever 22 is released.・
The lever 22 pushes the push rod 27 to release the free lock adjuster 21, adjusts the seat back 12 to an appropriate angle, and then returns the push button 38 to its original position. As the push button 38 is returned, the bell crank 33 is swung back, and the inner cable 45 of the push-pull cable 24 causes the movement of the bell crank 33 to the release lever 22. When transmitted, the release lever 22 is swung back, and the push rod 27 is released from the release lever 22 to fix the free lock adjuster 21. Since the free lock adjuster 21 is fixed in this manner, the seat back 12 is adjusted to the angle and fixed to the seat cushion 11. Of course, the angle of the seat back 12 can be adjusted steplessly by such a simple operation so that the seat cushion 1 can be adjusted.
Fixed to 1.
