Abstract
An actuator mechanism includes a attachment member fixed to a seat elevation adjuster and a controlling member placed between a driver member and the attachment member and can rotate together with an actuating lever. The driver member is located between the attachment member and a rotary member and fitted over a center shaft. There is formed a feed projection at one terminal portion of the driver member and its opposite terminal portion is placed face to face with a locking member. When the actuating lever is operated, the controlling member moves the driver member, which causes the locking member and the feed projection to engage with and disengage from the rotary member.
Claims20
An actuator mechanism for use in a seat elevation adjuster, comprising:
- a rotary member which is rotatable in the opposite directions about a center axis to actuate the seat elevation adjuster;
- a locking member which is engageable with the rotary member to keep the rotary member from rotating, and is disengageable from the rotary member to allow the rotary member to rotate;
- a driver member which is rotatable about the center axis, and is movable in a first direction perpendicularly intersecting the center axis and a second direction opposite to the first direction, and is engageable with the rotary member, the driver member:
- making the locking member to engage with the rotary member, and disengaging from the rotary member when moved in the first direction;
- and
- making the locking member to disengage from the rotary member, and engaging with the rotary member when moved in the second direction, whereby the rotary member is rotatable with a rotation of the driver member to actuate the seat elevation adjuster.
