An energy absorbing steering wheel assembly for use with a steering shaft includes an annular rim, a hub connecting the annular rim drivingly with an end portion of the steering shaft, a center covering member positioned at a generally center portion of the annular rim, and an energy absorbing structure positioned between the hub and the center covering member. The energy absorbing structure comprising a first portion connected to the center covering member, a second portion connected to the hub, a third portion which is sandwiched between the first and second portions, and brace members for minimizing displacement of the first portion and the third portion relative to each other and to the second portion when an impact load, exceeding a predetermined magnitude, is applied to the center covering member at an angle to the steering shaft.

A drive circuit for a wiper device includes reversible driving motors for alternately driving a pair of wiper assemblies in first and second directions. Each driving circuit includes a switching means and a means for detecting both ends of the wiper blade motions in the first and second directions. The switching means is operative to switch the direction of electric current supplied to an electric motor when the detecting means detects the end of wiper blade motion. Each driving circuit is connected to both of switching means so that it can reverse the current supplied to the driving motor when both of switching means detect the ends of the wiper assembly motion.

Drive circuit for a wiper device

A wiper device for wiping rain on a mirror surface of a rear-view mirror provided on the exterior of an automotive vehicle, includes a driving means of the wiper blade for driving the latter in first and second directions alternatively. The driving device comprises an electric circuit which includes a switching means and a means for detecting both ends of the wiper blade motions in the first and second directions. The switching means is operative to switch direction of an electric power supply to an electric motor when the detecting means detects the end of wiper blade motion.

Wiper device

A mirror apparatus having a wiper means intended to wipe a surface of a mirror supported on a mirror holder, wherein the wiper means comprises: a rubber ribbon for wiping the mirror surface; a pair of holders for supporting the rubber ribbon; and a pair of stays for supporting the pair of holders, respectively, to cause them to exert wiping operations, the rubber ribbon being provided with a curvable intermediate portion and a curvable end portion which are resulted from arrangement of the rubber ribbon being supported by the pair of holders excluding an intermediate portion and at least one end portion of the rubber ribbon, the pair of stays being coupled to each other by a shaft member at a site just above the intermediate portion of the rubber ribbon to provide for pivotable actions of these stays, that particular holder which located on the curvable end portion side of the rubber ribbon being coupled to its mating stay at a site located within a groove formed at a corresponding site of the rubber ribbon, to thereby reduce unwiped regions on the mirror surface and to enhance wiping efficiency.
