Abstract

The invention provides a pumping device for a seat of a vehicle. The pumping device for the seat of the vehicle comprises: a cam mechanism rotating along with a lever; a clutch mechanism receiving power from the cam mechanism; a housing accommodating the cam mechanism and the clutch mechanism therein; a brake mechanism accommodated in the housing to receive power from the clutch mechanism, and configured such that boss portions protrude along an outer circumferential surface thereof, outer end sides of the boss portions face an inner circumferential surface of the housing, and a pressing portion protruding from the clutch mechanism is disposed between a boss portion and a neighboring boss portion; and a brake roller provided at opposite sides of each of the boss portions of the brake mechanism to be disposed between the boss portion and the pressing portion.

Description

technical field [0001] The present invention relates to a pumping device for a vehicle seat that minimizes noise and wear by preventing contact of a brake mechanism with a housing. Background technique [0002] A conventional pumping device is a device that attaches to the seat and enables the seat occupant to manually adjust the height of the seat cushion to match the size of the seat occupant. [0003] If the seat occupant operates the operating lever handle installed on the side of the seat cushion clockwise or counterclockwise, the operating force of the operating lever handle is transmitted to the link mechanism through the seat pumping device to lift up according to the operating direction of the operating lever handle. Raise or lower the seat cushion to be able to adjust the height of the seat cushion. [0004] figure 1 A schematic diagram showing the components of a conventional seat pumping device. refer to figure 1 , the seat pumping device for a vehicle includ...
