摘要

A drive system (11) serves for reciprocating, between an extended position and a retracted position, a roll-up truck bed cover (6) above a truck bed (2), said roll-up truck bed cover (6) being composed of a rear profile (7), a plurality of elongate slats (8) that are hinged together, and has a front slat (9), said drive system (11) comprising at least one reciprocating means (11a) adapted for reciprocating the roll-up truck bed cover (6), and at least one reversible electric motor (16) adapted for driving the reciprocating means (11a). The at least one reciprocating means (11a) comprises at least one pulley system comprising at least one set of pulleys (13, 14) and at least one drive belt (12), which at least one set of pulleys includes a driven pulley (13) and an idle pulley (14), and the drive belt (12) is secured to the rear profile (7) of the roll-up truck bed cover (6).
