Patent ID: 8418406

Claim:
An acceleration and deceleration device ( 20 ) comprising an energy storage device ( 32 ), a cylinder ( 43 ) with first and second pistons ( 61 , 81 ) disposed in the cylinder ( 43 ) and being movable therein by means of a first carrier element ( 111 , 131 ), and a second carrier element ( 131 , 111 ) guiding one of the first piston ( 61 , 81 ) and the second piston ( 81 , 61 ) for movement in the cylinder ( 43 ) relative to the second and, respectively, the first piston ( 61 , 81 ), the carrier elements ( 111 , 131 ) being connected to the pistons ( 61 , 81 ) so as to be movable therewith over predetermined stroke lengths, the sum of the stroke lengths of the carrier elements ( 111 , 131 ) being greater than the length of the cylinder interior.
