Armrest with movable arm support particularly for vehicles

Arm rest with a moving arm support (1) comprises a pair of parallel guide rods (9, 10) moving in linear guides (2a, 2b) and connected to the arm support, and a basic support (2) with an arm rest holder (3, 4) and an adjusting device for the linear movement of the arm support. The arm support is an elongated hollow body with a flat under side (1a) having at one end an opening receiving the basic support and almost completely surrounding the basic support outside the arm rest holder. Inward-facing bearings (7, 8) arranged on the under side of the arm support receive the guide rods. The basic support is equipped with the linear guides for the guide rods. At least one spring-mounted locking element (12) and one spring-mounted brake element (11) arranged on the basic support constantly press against the under side of the arm support. The locking element is locked to the arm support in the various movement positions of the arm support. Preferred Features: The basic support is formed with the arm rest holder as a hybrid part consisting of a metal support part coated with plastic.
