ABSTRACT:
An arm connectible to a seat back and having teeth formed at one end is pivotally mounted to a seat bottom frame formed of first and second spaced, fixedly connected plates. A toothed drive gear mounted between the first and second plates and rotated by a drive unit meshingly engages the teeth on the arm to rotate the arm between infinitely adjustable positions. Aligned slots are formed in the first and second plates and receive opposed tenons of a rivet having the arm rotatably mounted about a central body portion. The tenons are angularly staked to the first and second plates such that one edge of each tenon farthest from the teeth on the arm is disposed in registry with the associated plate adjacent one edge of the slot and the diametrically opposed edge of each tenon is spaced above the opposite end of the slot in each plate to dispose the exterior end surface of each tenon at an acute angle with respect to the associated plate to urge the rivet and the arm in a direction toward the drive member to interlock the teeth on the arm with the teeth on the drive member.
