ABSTRACT:
A linear actuator useful for adjusting furniture includes a housing (1) with a reversible electric-motor (2) which, via a transmission (11, 13), drives a spindle (4) with a force absorbing bearing (16). On the spindle there is a nut (5) to which an actuation rod (86) is fixed surrounded by an outer tube (7). The actuator is with the actuation rod and a rear mounting mounted in the construction into which the actuator should be built-in. The motor housing is part of the supporting construction, as a console is fixed to this (10) with a fixing for the outer tube, spindle bearing and a rear mounting and is designed to absorb the forces occurring hereon. As the housing, as with previously known actuators, need not absorb and transfer forces, this can be made as a thin shell.
