Patent ID: 8746422

Claim:
A combined deceleration- and acceleration device ( 10 ) pre-installed in a housing ( 11 ) and comprising: a base part ( 21 ), a drag element ( 101 ) supported on the base part ( 21 ) so as to be movable thereon between an end position ( 7 ) and an opposite park position in which the drag element ( 101 ) is held in a form- or force-locking manner, a deceleration structure ( 41 ) comprising a cylinder piston unit ( 42 ) having a cylinder ( 51 ) and a piston ( 82 ) with a piston rod ( 87 ) being disposed in a vertical longitudinal center plane at one side of the base part ( 21 ), with the piston rod ( 87 ) being connected to the drag element ( 101 ) and an acceleration structure ( 91 ) including an energy storage element ( 92 ) arranged at the side of the base part ( 21 ) opposite the piston ( 82 ) and the piston rod ( 87 ) and having one end connected to the drag element ( 101 ), and the opposite end to the base part ( 21 ), the base part ( 21 ) being formed integrally with the cylinder ( 51 ) receiving the piston ( 82 ) of the cylinder, piston unit ( 42 ) and forming at least part of a guide structure ( 31 ) for the drag element ( 101 ), the combined deceleration and acceleration device, before installation thereof in the housing ( 11 ), being symmetrical with regard to said vertical longitudinal center plane.
