Abstract
A pumping device for a vehicle seat includes a cover configured to be coupled to one surface of a housing, a brake drum assembled in the housing and having a coupling protrusion provided at a center of one surface of the brake drum that is directed toward the cover, a locking plate positioned between the brake drum and the cover and having a through-hole configured to be coupled to the coupling protrusion, the locking plate being configured to implement a locking state in which the through-hole is coupled to the coupling protrusion, or the locking plate being configured to implement an unlocking state in which the through-hole is separated from the coupling protrusion.
Claims10
A pumping device for a vehicle seat, the pumping device comprising:
- a cover configured to be coupled to one surface of a housing;
- a brake drum disposed in the housing and having a coupling protrusion defined at a center of one surface of the brake drum that is directed toward the cover;
- a locking plate positioned between the brake drum and the cover and having a through-hole configured to be coupled to the coupling protrusion, the locking plate being configured to implement a locking state in which a rotation of the brake drum is restricted when the through-hole is coupled to the coupling protrusion as guide holes defined around the through-hole move in a state in which the guide holes are coupled to guide protrusions defined on one surface of the cover, or the locking plate being configured to implement an unlocking state in which the through-hole is separated from the coupling protrusion;
- and
- an elastic member disposed between the cover and the locking plate and configured to elastically support the locking plate.
