Abstract
A seat pumping device for a vehicle is mounted to a vehicle seat frame at a lower end part thereof, and may include: a housing having inner space provided therein and a slit hole provided in an upper end surface thereof; a clutch cam rotatably received into the inner space of the housing and having protrusions provided thereon, the protrusions protruding toward an outside of the housing by passing through the slit hole of the upper end surface thereof; and a lever bracket arranged at the outside of the housing to face the upper end surface of the housing, and having an insertion portion into which each of the protrusions of the clutch cam is inserted, so that the lever bracket is coupled to the clutch cam by coupling of the protrusion and the insertion portion to each other, and is rotated with the clutch cam.
Claims8
A seat pumping device for a vehicle, the device comprising:
- a housing having an inner space defined therein and at least one slit hole disposed in an upper end surface thereof;
- a clutch cam disposed in the inner space of the housing and having at least one protrusion disposed thereon, the at least one protrusion protruding toward an outside of the housing by passing through the at least one slit hole of the upper end surface thereof;
- and
- a lever bracket arranged at the outside of the housing to face the upper end surface of the housing, and having at least one insertion portion into which the at least one protrusion of the clutch cam is inserted, so that the lever bracket is coupled to the clutch cam by coupling of the at least one protrusion and the at least one insertion portion to each other, and is rotatable with the clutch cam,
- wherein the lever bracket is spaced apart by a predetermined distance from the upper end surface of the housing while the at least one insertion portion and the at least one protrusion are coupled to each other,
- wherein the at least one insertion portion of the lever bracket is at least one hole, and is disposed at a position corresponding to that of the at least one protrusion of the clutch cam,
- wherein the at least one hole comprises a first hole and a second hole which are different from each other in inner diameters, and
- wherein the inner diameter of the second hole is larger than the inner diameter of the first hole, and an end of the at least one protrusion is held by the first hole when the lever bracket is coupled to the clutch cam, such that the lever bracket is spaced apart by the predetermined distance from the upper end surface of the housing.
