Abstract: A motor vehicle seat recliner (10) includes upper and lower attachment members (12 and 14) joined at a hinge point (16). An adjuster (58) operates to establish a substantially fixed angular position between the members. An inertia latch (60) operative to disengage the adjuster from the upper attachment member as a function of recliner attitude and acceleration includes elements (52 and 62) defining cooperating engagement surfaces (98 and 99) which are relatively displaceable upon incipient movement of one of the members in a predetermined direction from a pre-latched position to a release position when the movement is relatively slow and to an engaged position when the movement is relatively fast.

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.
