Abstract
Abstract A knob is used on an adjustment member rotatable about an axis and having a periphery formed with a plurality of radially outwardly open recesses. This member may be the adjustment member of a motor-vehicle seat-angle adjuster. The knob comprises an annular collar closely surrounding the periphery of the adjustment member, a plurality of entrainment formations projecting inwardly from the collar into every other recess, and a plurality of hooks each engaging axially through the remaining recesses with the member. The hooks and the formations together transmit angular force between the member and the knob which is made of synthetic-resin material as one integral piece.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
In combination with an automotive-vehicle seat-angle adjustment device having a pair of hinge parts and means including an adjustment member rotatable about an axis and having a periphery formed with a plurality of radially outwardly open recesses for varying the relative position of said hinge parts, a knob having an annular collar closely surrounding said periphery, a plurality of entrainment formations projecting radially inwardly from said collar into respective recesses, and a plurality of radially outwardly deflectable hooks each engaging axially through a respective recess with said member, said hooks alternating with said formations around said periphery and each having a stem engaging through the respective recess and a hook head engaging behind said member, whereby said hooks and said formations can transmit force angularly between said member and said knob.
