Abstract

PURPOSE: To allow a seat to be turned after releasing the lock of a rotary seat frame by one motor through an inexpensive mechanical means. CONSTITUTION: In a seat for rolling stock, a rotary seat frame 2 is supported on a fixed frame 3 by a rotary shaft 9. Lock mechanism 41 for locking the rotary seat frame 2 to the fixed frame 3 is constituted of lock pins 37A, 37B and locking holes 40A, 40B. A motor 8 is connected to the rotary shaft 9 through a driving pulley 20, a wire 22, a driven pulley 13 and lock release cam mechanism 43. The lock release cam mechanism 43, a mechanical means, releases the lock mechanism 41 by the torque of the motor 18 in the state of the rotary seat frame 2 being separated from the motor 18 and stopped in the initial rotating stage of the rotary seat frame 2 and then connects the rotary seat frame 2 to the motor 18 to rotate it.

Immediately before reaching the state of FIG. 12,
The two recesses 50 of the upper cam plate 44, which do not overlap the recesses 51 of the lower cam plate 45, have their recesses killed by the circular outer periphery of the lower cam plate 45, and the cam followers 54 are on this circular outer periphery. If the recess of recess 50 is not killed in this way, cam follower 54 will not
Since the locking pin 37B comes into contact with the contact plate 36B immediately before entering the locking hole 40B, the locking pin 37B may not smoothly enter the locking hole 40B. However, in this embodiment, since the recesses of the two recesses 50 are killed by the circular outer periphery of the lower cam plate 45 as described above, there is no contact immediately before the locking, and the locking pin 37B is inserted into the locking hole 40B. Enter smoothly.

As described above, according to the rotating device of this embodiment, the unlocking cam mechanism 43 disconnects the rotary seat frame 2 from the motor 18 and stops the rotary seat frame 2 at the initial stage of rotation of the rotary seat frame 2. The lock mechanism 41 is released by the rotational force of the motor 18, and then the rotary seat frame 2 is connected to the motor 18 and rotated. Therefore, the release of the lock mechanism 41 and the seat 1 and the rotary seat frame 2 are performed by one motor 18. Therefore, it is not necessary to use an expensive separate motor or electromagnetic clutch just for releasing the lock mechanism 41. The unlocking cam mechanism 43, which is a mechanical means, does not require electric / electronic parts and can be constructed at low cost.

In particular, in this embodiment, since the lock of the seat 1 and the lock of the backrest 4 are configured to be released by the single unlocking cam mechanism 43, the railway vehicle having the reclining backrest 4 is used. In the passenger seat 1, the rotating device can be manufactured inexpensively with a small number of parts.

When the seat 1 is manually rotated, the foot pedal 7 is used to move the lever 52 through the wires 56 and 58.
A and 52B are rotated outward, the lock mechanism 41 is released via the wire 55, the backrest lock release lever 6 is driven via the wire 57, and then the rotary seat frame 2
Is manually rotated. At this time, since the drive pulley 20 is separated from the motor 18 by the slip clutch 19,
The passenger can easily change the direction of the seat 1 with a light force without reversely driving the motor 18.
