後チルト機構。[Scope of Claim for Utility Model Registration] (1) An upper frame that is disposed opposite to the lower frame and has an opening on the inside, and the upper and lower ends have outwardly extending shafts and are interlocked with each other. It also has a pair of left and right link arms whose lower ends are pivotally connected to the lower frame, and a pair of link mechanisms spaced apart in the front and rear between the upper frame and the lower frame, and a pair of link arms at the upper ends of the front and rear link mechanisms. Supported by an extending shaft,
The rollers are arranged so as to be able to roll within the opening of the upper frame, the connecting links that rotatably connect the upper frame and the lower frame, and the swinging of the front and rear link mechanisms are individually regulated and operated. A front and rear tilting mechanism for a seat, comprising front and rear locking means for individually locking and unlocking each link mechanism by operating a lever. (2) The locking means has a plurality of teeth that can be engaged with the extending shaft at the upper end of the link mechanism, and is attached to the lock plate so as to be swingable in the axial direction of the extending shaft, and is integrated with the lock plate. The seat according to claim 1, comprising: an operating lever that is swingably provided; and biasing means that biases the teeth of the lock plate in the direction of engagement with the extending shaft of the upper end of the link arm. Front and rear tilt mechanism.
