A latch can be movably mounted to each of the side rails for movement between an unlocked position and a locked position. A release actuator can be movably mounted to the rear header to extend adjacent both latches for movement between a non-release position and a release position. When the rear header is seated in the rear header seat and the release actuator is in the non-release position, each latch engages the rear header in the locked position to lock the rear header and side rails together. When the rear header is seated in the rear header seat and the release actuator is moved toward the release position, the release actuator engages both latches and moves the latches to the unlocked position to unlock the rear header from both of the side rails.

A tonneau cover system for covering a space. The system includes a frame having rails. A cover is disposed over the frame for covering the space. A block, a receiver, an anchor and a latch are all coupled to the frame. A mechanism is disposed between the block and the receiver and provides adjustment to the frame by moving the receiver, the anchor and the latch as a unit between an initial adjustment position and a final adjustment position. The mechanism also provides tension to the cover when the latch is engaging the frame.

A dual action truck cover provides two modes, actions or ways to access contents in a truck bed. Side rails can be mountable to a cargo box so as to be pivotable between a raised position to provide a rear opening in an open pivot arrangement, and a lowered or closed pivot arrangement. The side rails can be spaced apart to define an inter-rail area therebetween. A door can include a plurality of elements hingedly coupled together and extending between the side rails and movable between a closed door arrangement wherein the elements cover the inter-rail area, and an open door arrangement in which the elements are positioned to permit access through the inter-rail area. The door can move between the open and closed arrangements by rolling up the hingedly coupled elements together or folding the elements together.

In the coupling of bi-directional, non-freewheeling-type DC motors (24,25) to the pulling spool (23) of a canopy (11) deployment strap (21,22) and to a take-up roller (15), ratchet gears (26,27) assure automatic alignment and synchronization of the deployment and retraction mechanisms. The reverse direction rotation of the unwinding motor can be uninhibited through the slipping of its ratchet gear when the winding motor is slow to take up the pulling strap or the tarp (11) being wound thereon. The slipping provides sufficient slack to accommodate changes of spool and roller diameters as more material is successively wound thereon. A friction brake acting against a flange of die spool keeps it from spinning freely when not engaged by the motor. Winding motors can be protected against excessive power use by measuring the level of drawn current with a digital ammeter. If the current exceeds a threshold level of operation, a timer is started. As soon as a given absolute safe period of operation is surpassed, a breaker switch is tripped interrupting the motor power supply. A plural number of trip points can be programmed into the device.

A tarpaulin cover system includes a drive unit for moving the tarpaulin selectively into covering and uncovering positions. The drive unit comprises first and second drive sprockets and a rotatable actuator sprocket with all of the sprockets spaced from and out of contact with each other. An idler sprocket is provided between the actuator sprocket and the drive sprockets. All of the sprockets are interconnected by a chain engaged with teeth with the chain extending partially around each sprocket whereby rotation of the actuator sprocket causes the drive sprockets to move in the intended directions. This motion is transmitted to drive pulleys which drive cables to control the position of the tarpaulin.

Disclosed are embodiments of a retractable tonneau cover for a vehicle that has been modified in order to generally minimize the size of a housing of the tonneau cover, providing more vehicle cargo space for a user. The modified retractable tonneau cover can be automatically closed through an electronic system.

The present disclosure relates to an electric lift gate and a vehicle. The electric lift gate includes: two side bars opposed and spaced apart, and the two side bars being provided with a guiding groove, respectively, the guiding groove extending along a length direction of the side bar; a roller shutter assembly disposed between the two side bars, two opposite sides of the roller shutter assembly being slidably disposed in the corresponding guiding grooves, respectively; a winding assembly cooperating with the roller shutter assembly in a driving manner; and a driving assembly connected to the winding assembly, and configured to drive the winding assembly to rotate, so as to drive the roller shutter assembly to wind or unwind.

A tonneau cover configured to cover a cargo box of a vehicle, comprising: (a) opposing side rails configured to attach to opposing sides of the cargo box; (b) a slat extending between and supported by the opposing siderails, wherein the slat is configured to move along the siderails; and (c) a drive system that drives the slat and moves the slat along the side rails from a closed position where the slat covers an interior of the cargo box, to an open position where the interior of the cargo box is exposed, wherein the drive system is controlled wirelessly by a remote device, by a sensor located along the cargo box, or both.

A retractable cover system includes a frame that provides an opening and a drive system. A flexible cover is configured to slide relative to the frame between first and second positions within the opening in response to actuation of the drive system. Multiple spaced apart bows are configured to slide relative to the frame and relative to the flexible cover.
