Abstract
A rotational latching device for use with a damper device comprising a cylinder and a piston so as to hold the piston in the closed position includes a rotating latching member and a heart-shaped cam part. The cam part includes a V-shaped portion. The latch member includes a latch guide pin which is retained in a V-shaped portion of the cam part in the closed position and is unlatched therefrom when the front end of the piston is moved slightly into the cylinder. The rotating latch member comprises a one-piece construction, can be easily formed by injection molding, and is readily assembled.
