Abstract A detent component for use in a detent assembly of the kind capable of latching a linearly movable member in a predetermined position relative to a fixed member includes a mounting piece whereby the component can be secured to either the movable or the fixed member of a pair of relatively linearly movable members. Additionally, there is a cam follower carried by the mounting piece which is engageable with a detent cam form on the other of the pair of members. The cam follower is defined by an upturned end region of a first limb of a hairpin type spring the second limb of which engages a stop on the mounting piece. The junction region of the first and second limbs defining a loop encircling an anchor post on the mounting piece and the first limb abutting a pair of spaced abutments on the mounting piece. The pair of abutments are positioned so that in use they are aligned parallel to the direction of relative movement of the members, and the resilience of the spring causes the first limb to engage the abutments so that the abutments define a rest position of the limb which, in use, is parallel to the direction of relative movement of the members.
