Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an auxiliary seat attached to a vehicle or the like, and more particularly to an auxiliary seat provided with a locking device.

(Prior Art) In vehicles used by many people such as buses, so-called auxiliary seats are provided in addition to general seats such as fixed seats. The auxiliary seat is used as a seat for a person who uses a vehicle or a crew member, and the auxiliary seat is generally pulled out to the aisle side for use.
That is, when this type of auxiliary seat is not used, it is stored in a storage frame provided on an armrest, a wall, etc.
(See Japanese Laid-Open Patent Publication No. 2-21532) The seat is pulled out from this when necessary.

A conventional auxiliary seat of this type is generally configured as follows. That is, an auxiliary seat of this type is composed of a seat plate and a backrest rotatably connected to the seat plate, and the seat plate is rotatably connected to a storage frame by an arm or the like. Then, in order to maintain the state of being housed in the storage frame, an elastic material such as a spring is interposed in the arm or the storage frame, and especially the seat plate in the folded state is stored in the storage frame. It was structured to pull in. For this reason, the elastic material such as the above spring is generally strong, and when trying to pull out the seat plate to use the auxiliary seat, the elastic material such as the spring is used. I had to apply a considerable force to the seat to resist it.

In addition, such an auxiliary seat can be freely pulled out and used by the user as it is, so that even if the vehicle is crowded, a person in front of the aisle can get in the way. It was possible to use this auxiliary seat without permission, which sometimes obstructed the passage of other people. For this reason, the vehicle manager had to explain each time not to use the auxiliary seat.
