A seat arrangement in a motor vehicle, particularly in a rear thereof, comprises a base (4) and a back rest (6) which is pivotable at a lower region (8) to provide a selected angle of inclination. Adjustable latching means (10) is adapted to be secured to a first member in the form of an upper region (14) of at least one side of the back rest or to at least one body part of the vehicle. Rigid striker means (18) having spaced first and second striker portions (20, 22) is adapted to be secured to a second member in the form of the other of the back rest and the body part. The adjustable latching means (10) comprises: a rotatable cam member (12) cooperating with the striker means (18); an elongate slider (24) slidably secured to the first member and biased towards a cam surface (30) of the cam member. The arrangement is such that a first portion of the slider engages the cam surface and a second portion of the slider is adapted for manual retraction of the slider away from the cam surface against the biassing force. The cam member (12) further has first and second slots (44, 42) such that in a first position of the back rest (6) the first striker portion (20) of the striker means engages the first slot (44), with the cam member (12) orientated such that the first portion of the slider also engages the first slot (44) to effect locking of the back rest in this first position; and in a second position of the back rest (6) the second striker portion (22) of the striker means engages the second slot (42), with the cam member (12) orientated such that the first portion of the slider also engages the second slot (42) to effect locking of the back rest (6) in this second position.
