Abstract: A motor vehicle seat is disclosed which can pivot with respect to its underframe in a predetermined direction about a rear axis a transverse direction extending perpendicularly to the travel direction of the vehicle. The seat is supported on the underframe by means of a front deformation element arranged at a distance from the rear axis. The deformation element serves to lessen the severity of injury to person colliding with the seat backrest from behind. The deformation element is designed as a foamed material block surrounded by a shell. The upper and lower shell surfaces of the shell are respectively provided with fastening devices for fixing to the underside of the seat and to the underframe. The shell has predetermined bending sections which form the folding lines during pivoting of the motor vehicle seat caused by an accident.

Abstract: A line network for at least one of hydraulic and pneumatic media with the line network being adapted for use in motor vehicles such as buses as well as in aircraft, machines, or buildings. The line network is formed by extruded sections or members instead of conventional individual lines with each or the sections of members including a plurality of tubular enclosed sections which define the lines as well as chambers or reservoirs for accommodating pneumatic and hydraulic media or the like. Connection to the lines and/or chambers can be accomplished throughout the entire length of the extruded members or sections. The extruded members or sections may be formed from aluminum, aluminum alloys, and, in certain applications, of a plastic material.
