Definitions
- the present invention relates to a height adjustment device for an armrest of a vehicle seat.
- a height adjustment device that has a lock spring and a shaft arranged in a coil portion of the lock spring, and holds the armrest at an arbitrary position by frictional resistance generated between the coil portion and the shaft.
- a height adjustment device that has a lock spring and a shaft arranged in a coil portion of the lock spring, and holds the armrest at an arbitrary position by frictional resistance generated between the coil portion and the shaft.
- the known device has a problem that requires an operation lever in order to increase and decrease the frictional resistance between the coil portion and the shaft.
- Another object of the present invention is to provide an armrest height adjusting device that can be operated easily.
- FIG. 1 is a side view of a vehicle seat provided with a height adjusting device for a hamlet according to the present invention.
- FIG. 2 is an exploded perspective view of a lock device of the height adjustment device.
- FIG. 3 is an exploded perspective view of the lock device.
- FIG. 4 is a side view showing the seat back frame and the armrest frame at the lower limit position.
- FIG. 5 is a perspective view of the lock device when the armrest is at the lower limit position.
- FIG. 6 is a perspective view of the lock device when the armrest is at the top position within the range of use.
- FIG. 7 and FIG. 8 are perspective views of the lock device when the firmware shifts from the use range to the storage range.
- FIG. 9 is a perspective view of the lock device when the transfer of the firmware to the storage range is completed.
- FIG. 10 is a perspective view of the lock device when the armrest is at the upper limit position.
- FIG. 11 is a perspective view of the lock device when the armrest moves from the storage position to the vicinity of the lower limit position.
- Fig. 12 shows the relationship between the window of the spring cover and the hook of the bent plate.
- the vehicle seat 1 according to the present invention comprises a seat bottom 2 slidably mounted on a vehicle body (not shown), and a seat back 3 rotatably supported on the seat bottom 2 and capable of adjusting a tilt angle. And an armrest 4 provided on the side of the seatback 3.
- a bracket 6 is fixed to a seat back frame 5 of the seat back 3.
- the arm frame 8 of the armrest 4 is rotatably mounted on a bracket 6 (frame 8) by a shaft 7 in the left-right direction.
- a lock device 40 is provided between the base of the arm frame 8 and the seat back frame 5.
- the armrest 4 can be displaced between a lower limit position L and an upper limit position H, as shown in FIG.
- Armrest 4 is normally used within range A.
- the armrest 4 is held at an arbitrary position by the lock device 40. That is, the displacement of the armrest 4 toward the lower limit position L is regulated by the lock device 40.
- the lock device 40 is moved toward the upper limit position H of the armrest 4. Is not regulated.
- the locking device 40 does not hinder the rotation of the armrest 4 in the storage range B set above the use range A. In other words, armrest 4 rotates freely in storage range B.
- the lock device 40 does not prevent the rotation of the armrest 4 within the use range A.
- the lock function of the lock device 40 within the use range A is restored when the armrest 4 is substantially displaced to the lower limit position L.
- the lock device 40 has a lock spring 11.
- the coil portion 11 A of the spring 11 is arranged on the outer periphery of the collar 10, and the shaft 7 is inserted into the collar 10.
- One end of the collar 10 passes through the bracket 6 and is fixed to the arm frame 8. Therefore, the collar 10 rotates integrally with the armrest 4.
- the first bent leg portion 11 B of the lock spring 11 is engaged with the engagement hole 14 of the sub bracket 13 fixed to the bracket 6.
- the second straight leg 11C protrudes long in the radiation direction of the coil 11A.
- the coil portion 11 A is in close contact with the collar 10 with an appropriate strength.
- a spring cover 30 is fixed to the other end of the collar 10.
- the spring cover 30 includes a disc-shaped plate 31 and a bent flange 38 extending from the outer peripheral edge of the plate 31 toward the arm frame 8.
- the bent flange 38 has a window 41 in which the second straight leg 11C is stored.
- An unlocking contact wall 32 substantially parallel to the axis of the shaft 7 is formed on one side of the window 41, and a return inclined wall 39 is formed on the other side of the window 41.
- the coil 11 A In a state where the straight leg 11 C is not subjected to an external force, the coil 11 A is in close contact with the roller 10 with an appropriate strength.
- the armrest 4 is held at an arbitrary position within the use range A by the frictional resistance due to this contact. Armless driver's elbow
- the armrest 4 (color _ 10) attempts to rotate downwards when placed on the coil 4
- the coil section 11 A becomes shorter in diameter and wraps around the collar 10 strongly, and
- the frictional resistance between the collar 11A and the collar 10 increases instantaneously. The increased frictional resistance prevents the armrest 4 from rotating downward.
- the sub-bracket 13 has a bent plate 25 extending parallel to the axis of the shaft 7 toward the seat back frame 5, and the bent plate 25 has a straight leg 11C.
- Formable hooks 24 are formed.
- the hook 24 has an inclined guide cam surface 23 for guiding the straight leg 11C into the hook 24, and an unlock holding surface 22 for holding the straight leg 11C at an unlock position.
- the unlock holding surface 22 should be shaped parallel to the axis of the shaft 7 or reputed to have a gentle slope as shown in Fig.12. Is done.
- a passage 26 is formed between the guide cam surface 23 and the unlock holding surface 22.
- the bending plate 25 has an inclined surface 27 connected to the passage 6.
- the edge of the unlocking contact wall 32 of the spring cover 30 matches the edge of the unlock holding surface 22 or overlaps with each other as shown in FIG.
- the armrest 4 rotates further upward from the state of FIG. 6 in which the arm frame 8 is at the top position within the use range A, as shown in FIG. 7, the armrest 4 is pushed by the unlocking contact wall 32.
- the straight leg ⁇ 1 C thus brought into contact with the guide cam surface 23 is guided into the hook 24.
- the straight leg 11 C moves into the hook 24 as shown in FIG. 8, the straight leg 11 C comes off the unlock contact wall 32, and then the straight leg 11 C becomes the coil portion as shown in FIG. 9. It comes into contact with the unlock holding surface 22 with the elasticity of 1 1 A.
- the position where the straight leg portion ⁇ 1 C contacts the unlock holding surface 22 of the sub bracket 13 is a position below the storage range B of the armrest 4.
- a closed wall 33 orthogonal to the axial direction of the shaft 7 is formed on the bent flange 38.
- the closing wall 3 3 is connected to the end of the unlocking contact wall 3 2 You.
- the closing wall 33 substantially closes the passage 26 of the hook 24, and the straight leg 11 1 C is prevented from coming off the unlock holding surface 22.
- FIG. 10 shows a state when the armrest 4 is moved to the upper limit position H.
- a stopper 34 is provided in parallel with the axis of the shaft 7. The stopper 34 prevents excessive rotation of the armrest 4.
- the structure is simple because the armrest 4 functions as an operation lever.
- the working range A of the armrest 4 can be easily changed by changing the distance between the unlocking contact wall 32 of the spring cover 30 and the inclined wall 39 (end portion 37). .
- the closing wall 33 of the window portion 41 closes the passage 26 of the hook 24 and the straight leg portion 1 1 Prevents C from falling off hook 24. Therefore, when the armrest 4 is displaced from the storage range B toward the use range A, the armrest 4 can be smoothly displaced to the lower limit position L of the use range A.
