Abstract
Abstract A device for mounting an operating lever for operating a gas pressure control plug of a gas spring is disclosed, in which the operating lever is in contact with the free end of the gas pressure control plug supported on a mounting frame of a seat or the like. The operating lever has a short shaft provided at an end and extending perpendicular to the axis of the gas spring. The short shaft is pressure fitted in an engagement groove, which is provided in a synthetic resin bearing block secured to a mounting frame and has a more-than-semicircular arcular sectional profile.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A device for mounting an operating lever for a gas spring, in which said operating lever is in contact with the free end of a gas pressure control plug of the gas spring while supported on a mounting frame of a seat or the like, which comprises: a short shaft provided at an end of said operating lever and extending perpendicular to the axis of said gas spring; an elongated synthetic resin bearing block secured to a mounting frame; the bearing block having opposite front and rear walls with a semi-arcuate engagement groove extending longitudinally between the front and rear walls; the bearing block also having a mounting portion with a longitudinally extending mounting groove below said engagement groove which opens towards one of said bearing block walls for receiving a portion of said mounting frame; and said short shaft being press fitted in said engagement groove such that it will not be readily detached therefrom.
