Description

  The present invention relates to a vehicular seat provided on a vehicular seat for operating a position changing mechanism that locks a component part of a vehicle seat such as a seat back in a fixed position and releases the lock when the position of the component part is changed. The present invention relates to a sheet operating lever device.

  A vehicle seat on which a passenger is seated is installed in a vehicle such as an automobile. The vehicle seat includes a seat cushion on which an occupant is seated and a seat back that is a backrest of the seated occupant. Such a vehicle seat is known in which a seat back position changing mechanism such as a reclining mechanism or a locking mechanism is provided so that the fixing position of the seat back can be changed. According to the vehicle seat provided with these seat back position changing mechanisms, the backrest angle of the seat back can be changed, or the seat back can be positioned so as to overlap.

  On the other hand, such a vehicle seat is provided with an operation lever device for operating the above-described seat back position changing mechanism. This operation lever device includes an operation lever that is operated by a passenger. This operation lever is connected to the above-described seat back position changing mechanism via an operation cable. The operating lever device is configured to move the operating cable when the operating lever is rotated, and releases the lock by the seat back position changing mechanism that has been locked until then. In the vehicle seat that is unlocked, the backrest position of the seat back can be changed as described above.

  On the other hand, there are cases in which a heavy load such as a wine case is loaded on the rear side of the vehicle seat in an automobile in which the vehicle seat is installed. When an automobile loaded with such a heavy load suddenly stops, the load may collide with the vehicle seat located on the front side, and suddenly impact the vehicle seat. Then, an inertial force is generated in the operation lever device due to the received impact, and the operation lever (including a member connected to the operation lever) is arbitrarily rotated by the inertial force and is locked until then. The lock by the seat back position changing mechanism that has been performed may be released. If the lock by the seat back position changing mechanism is released in this way, the seat back moves at a place unintended by the occupant, which is inferior.

  In order to improve such a state of inconvenience, a technique is known in which the lever device described above is provided with a lever rotation restricting mechanism that restricts the rotation of the operation lever at the initial position before the rotation operation. (For example, refer to Patent Document 1). In this disclosed technique, when the operation lever is rotated, an operation is performed to release the rotation restriction of the lever rotation restriction mechanism (pressing the push button in Patent Document 1). In addition, it is possible to prevent the seat back from being unlocked.
