RETRACTABLE TOP FOR A VEHICLE

摘要

A retractable roof for a vehicle comprises two telescopic tube arrangements disposed on opposite sides respectively of the roof which comprises first and second panels (1) and (2). Each arrangement comprises three tubes (7, 8 and 9) dimentioned mentioned to be telescopically received one within the other, of hollow elliptical cross-section and made of carbon fibre. Expandable bags are disposed inside tubes (7) and (8). Each bag is disposed within a braided sock made of a low friction material to control movement and diameter of the bag within the corresponding tube, and facilitate its expansion and contraction. By supplying and withdrawing pressure fluid to and from the bags, the roof may be moved between extended and contracted positions. Expandable seals are disposed between adjacent roof panels and between those panels and the front and rear screens of the vehicle.
