Abstract

The invention relates to a gas spring (1) with a pivoting cover (4) for absorbing non-axial loads, thus preventing the stress resulting from said loads from causing failures and reducing the working life of the spring (1). The cover (4) is divided into a fixed external portion (4a) that is rigidly secured to the body (2), and a pivoting internal portion (4b) having a hole over which the shaft (3) slides, the two portions (4a, 4b) being connected via an at least partially spherical contact surface, such that the pivoting internal portion (4b) is orientable. The spring (1) also comprises an additional O-ring seal (5) between the fixed external portion (4a) and the pivoting internal portion (4b) of the cover (4) for preventing gas leaks. The end of the shaft (3) also has a sliding element (7) that can move radially to absorb horizontal movements.
