A folding seat 10 comprises a support structure 13, a backrest 11 and a seat base 12 pivotally mounted on the support structure for pivoting between a seating position (Fig. 1) with the seat base extending generally horizontal and the backrest generally vertical, a table position (Fig. 2) with base and backrest both extending generally horizontal, and a stored position (Fig. 3) with the base and backrest both extending generally vertical. The seat further comprises a first over-centre spring mechanism (19, Fig. 2) acting on the seat base to bias the seat base towards its generally horizontal position or its generally vertical position, depending on which side of its over-centre position the base is located. Also provided is a second over-centre spring mechanism 28 which acts on the backrest to bias the backrest towards its generally vertical position or its generally horizontal position, depending on which side of its over-centre position the backrest is located. |
