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.
Claims9
A pumping device for a vehicle seat, the pumping device comprising:
- a cover configured to be coupled to one surface of a housing and having guide protrusions defined on one surface of the cover,
- 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 further having guide holes defined around the through-hole,
- wherein the locking plate is 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 the guide holes defined around the through-hole move in a state in which the guide holes are coupled to the guide protrusions defined on one surface of the cover, or
- 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.
