Abstract
A seat (10) for a utility vehicle comprising a base (12) and a back support (14) is provided. The back support has an asymmetric profile (18) which includes a cut-away portion (20) at a position corresponding to a user's first shoulder, and a mounting point (25) corresponding to a point located above the user's second shoulder for attachment of a three-point harness (22, 24). Provision of the cut-away portion on one upper corner of the seat maintains a portion on the opposite side of the seat for location of the three-point harness thus delivering increased freedom of movement for the operator whilst incorporating safety requirements.
