Detailed Description

The utility model provides a car seat leg holds in palm adjustment mechanism, including driving motor 1 and book wire reel 2, driving motor 1's output gear 11 and two follow-up gears 12 constant mesh, two follow-up gears 12 respectively through clutching mechanism with a left side, two couples of book wire reel 2 on the right side, the reverse wind of both ends of same root cable 3 is on book wire reel 2, it is located between two parallel guide 5 to roll up wire reel 2, install slider 6 on the

guide rail

5, 5 both ends of guide rail are equipped with fixed pulley 4 and draw the middle section of cable 3 to open for the straight line, 6 fixed connection of slider in the middle section of cable 3, whether rotate along with driving motor 1 through clutching mechanism control book wire reel 2. The rotation of the wire coiling disk can enable one end of the inhaul cable 3 to be coiled and the other end to be uncoiled, so that the middle section of the inhaul cable 3 can move up and down between the two fixed pulleys 4, and the sliding block 6 is driven to move on the guide rail 5. The seat depth adjustment is realized by the synchronous motion of the leg supports arranged on the sliding block 6.

The clutch mechanism comprises a clutch gear 14 arranged in the center of the follower gear 12, a spring 13 is arranged at the front end of a rotating shaft of the clutch gear 14, the wire winding disc 2 is sleeved on the rotating shaft, the rear end of the rotating shaft of the clutch gear 14 penetrates through the center of the wire winding disc 2, the clutch gear 14 and the rotating shaft of the clutch gear can axially slide in the wire winding disc 2, the wire winding disc 2 cannot be driven to move by the axial sliding of the clutch gear 14, but the rotation of the clutch gear 14 can drive the wire winding disc 2 to rotate.
