ABSTRACT:
A locking device for a seat suspension provided in a seat for use in a vehicle such as an automobile is disclosed in which an upper frame attached to the seat proper side is supported via front and rear links to a lower frame fixed to the vehicle floor side in such a manner that it can be oscillated in a vertical direction relative to the lower frame, the upper frame is provided with engagement pins, and the lower frame is provided with lock plates engageable with the engagement pins. The lock plates are connected through link piece means with a shaft slidable longitudinally by an operation lever and also can be engaged with or disengaged from the engagement pins by the longitudinal sliding movements of the shaft. When the lock plates are engaged with the engagement pins, the link-piece means is connected with the shaft in a direction perpendicular thereto. Thus, when such a force is caused to act on the lock plates as to remove them from their respective engaged positions, such force will be applied through the link-piece means to the shaft perpendicularly, so that the engagement can be positively maintained.
