Title:
SEAT LIFTER DEVICE
Document Type and Number:
Japanese Patent JP2022076652
Kind Code:
A
Abstract:
To provide a seat lifter device capable of appropriately preventing a slip of a seat in a lowering operation.SOLUTION: A seat lifter device 10 includes an output shaft 22 for operating a seat by lifting/lowering in response to a rotary operation amount of an operation handle. The device includes a slip prevention part D arranged in a power transmission route between the output shaft 22 and a feeding part for performing feeding by the input rotary operation amount. The slip prevention part D transmits the rotation of the feeding part to the output shaft 22 by the operation of the operation handle when rotated from a neutral position, but prevents a slip of the output shaft 22 by fitting with a cover 24 by repulsive force by receiving an operation of the slip when the output shaft slips to be rotated before the feeding part against friction force of a friction generation part in a case where the operation handle is rotated in a direction to lower the seat.SELECTED DRAWING: Figure 38
