Problems solved by technology

[0011] When the clutch cam 20 is not prevented from undesired movement, there is a problem that the undesired movement of the clutch cam 20 is transmitted to the lever bracket 30, inevitably resulting in an undesired movement of the lever (not shown) itself
As a result, the undesired small movement of components inside the seat pump increases as it is transmitted to the longer lever, causing great inconvenience to the occupant

Abstract

Disclosed is a seat pumping device for a vehicle. The seat pumping device includes: a housing having a through hole formed therein; a clutch cam positioned on an inside of the housing and coupled suchthat a coupling protrusion protruding outwardly of the housing through the through hole is turnable relative to the housing; a lever bracket positioned on an outside of an upper surface of the housing so as to face the clutch cam with the housing interposed therebetween, the lever bracket being coupled to the coupling protrusion of the clutch cam to be turned integrally with the clutch cam; and asupporting portion protruding from one of the upper surface of the housing and a lower surface of the lever bracket toward a remaining one, the upper surface of the housing and the lower surface of the lever bracket facing each other, the supporting portion supporting the lever bracket and the housing so as to be spaced apart from each other at a regular interval.

Description

technical field [0001] The present invention generally relates to a seat pumping device for a vehicle, and more particularly, to a seat pumping device for a vehicle in which the seat pumping device is capable of reducing component failures generated inside the device. desired movement. Background technique [0002] As is well known, a seat lift device for a vehicle refers to a device mounted to a seat to allow an occupant of the seat to manually adjust the height of the seat. Specifically, when the occupant on the seat operates the operating lever installed on the side of the seat cushion clockwise or counterclockwise, the operating force applied by the occupant on the operating lever is transmitted to the link mechanism to make the seat cushion upward or downward. Move Downward. Here, the lifting device for the vehicle provided between the operating rod and the link mechanism transmits the torque of the operating rod to the link mechanism. [0003] For this reason, as di...
