SEAT DRIVING APPARATUS

摘要

A seat driving apparatus includes: a rotary motor; operation members arranged so as to correspond to positional adjustment mechanisms; clutch mechanisms arranged so as to correspond to the positional adjustment mechanisms and selectively connecting the corresponding positional adjustment mechanism with the rotary motor; switch cam members sharing a same first rotary axis so as to be pivotally supported thereabout, respectively joined to the operation members so as to be driven therewith, and respectively including switch cam portions; a switch lever pivotally supported about a second rotary axis, including a pressed portion and regulation portions, causing the pressed portion to be pressed by the corresponding switch cam portion, and causing the regulation portion to block turning tracks of other switch cam portions; and a switch electrifying the rotary motor through a polarity coping with a turning direction in response to the turning of the switch lever.

1. A seat driving apparatus comprising:
a rotary motor; a plurality of operation members that are individually arranged so as to correspond to a plurality of positional adjustment mechanisms; a plurality of clutch mechanisms that are individually arranged so as to correspond to the plurality of positional adjustment mechanisms and selectively connect the corresponding positional adjustment mechanism with the rotary motor in accordance with an operation of any one of the plurality of operation members; a plurality of switch cam members that share a same first rotary axis so as to be pivotally supported thereabout, are respectively joined to the plurality of operation members so as to be driven therewith, and respectively include switch cam portions; a switch lever that is pivotally supported about a second rotary axis different from the first rotary axis of the plurality of switch cam members, includes a pressed portion protruding in a radial direction and a pair of regulation portions protruding in the radial direction from both sides interposing the pressed portion in a circumferential direction, causes the pressed portion to be pressed by the corresponding switch cam portion of the switch cam member so as to turn when any one of the plurality of operation members is in operation, and causes the regulation portion to block turning tracks of other switch cam portions of the switch cam members during the turning thereof; and a switch that electrifies the rotary motor through a polarity coping with a turning direction in response to the turning of the switch lever.
