Abstract

A tension control assembly for a flexible tonneau cover system of a pick-up truck has an adjustable engagement plate and a screw assembly. The adjustable engagement plate has an engagement hook to selectively engage in one of engagement holes formed on a side rail, and further has a positioning hole to position the screw assembly according to the engagement relationship between the engagement hook and the engagement holes, so that the adjustable engagement plate and the screw assembly can be used to adjust and stably keep a longitudinal position of a front header in relation to a length direction of the side rail, so as to prevent from causing vibration noise. Meanwhile, a transverse position of the front header in relation to a width direction of the side rail can be simultaneously adjusted during adjusting the longitudinal position of the front header.

Dependent claims

A tension control assembly for a flexible tonneau cover system of a pick-up truck, being installed between a front end of a side rail and one end of a front header, and comprising:

an adjustable engagement plate sandwiched between the front header and the side rail, and having a positioning hole and an engagement hook to selectively engage in one of engagement holes formed on the front end of the side rail, wherein the engagement hook is formed on a rear edge of the adjustable engagement plate and the positioning hole is formed on a position close to a front edge of the adjustable engagement plate;
and
a screw assembly having a screw member and a nut member, wherein the screw member is formed with a head portion and a thread rod portion, the head portion is slidably installed in a groove of the front header, the thread rod portion passes through the positioning hole of the adjustable engagement plate and an oval-shaped hole on the front end of the side rail in turn to screw-connect with the nut member, so that a transverse position of the front header in relation to a width direction of the side rail is adjusted and stably kept, while the positioning hole of the adjustable engagement plate positions the thread rod portion of the screw assembly according to an engagement relationship between the engagement hook and the engagement holes, so that a longitudinal position of the front header in relation to a length direction of the side rail is adjusted and stably kept.
