Problems solved by technology

[0007] However, conventionally, the clutch unit has a T-shaped protrusion to operate the brake roller. At this time, since the protrusion of the clutch unit makes contact with the housing intermittently, there is Such a problem that the operating force decreases during operation and a sense of difference is created
[0008] In addition, due to the provision of a pair of elastic bodies on opposite sides of the T-shaped protrusion, the number of parts increases and the manufacturing cost increases

Abstract

A pumping device for a seat of a vehicle is proposed. In the pumping device, a plurality of pressure members is provided along an outer circumferential surface of a brake drum, and braking operation is performed through the pressure members moved when the brake drum rotates, so that friction between the brake drum and a housing can be avoided and thus deterioration of operational performance is prevented. In addition, the shape of the brake drum is simplified and the number of components is reduced, so that weight and size of the pumping device, and production cost are reduced, and fuel efficiency increases.

Description

technical field [0001] The present invention generally relates to a pumping device for a vehicle seat, wherein the pumping device is configured to minimize interference between components, thereby preventing Deterioration of operating force, and simplified construction to reduce production costs. Background technique [0002] In general, seats provided at front and rear regions of a car of a vehicle, such as a driver's seat and a passenger seat, are provided with various conveniences for passenger comfort. [0003] As a convenience device, the seat of the vehicle has functions such as a sliding function and a reclining function. The sliding function can adjust the position of the seat by pushing and pulling the seat forward and backward according to the body shape of the passenger; the reclining function can adjust the position of the seat back. slope. [0004] In addition, in recent years, a pumping device having a seat lifting function has been installed in a vehicle, th...
