Abstract: Particular embodiments may provide a tonneau system for a vehicle. The tonneau system may be movable between an extended configuration and a retracted configuration. The tonneau system may include a cover, a beam, and rails. The cover may have two side edges and a tail edge, the beam may be coupled to the tail edge of the cover, and the rails may be coupled to the side edges of the cover. In some embodiments, the beam and the rails bi-directionally tension the cover when the tonneau system is in the extended configuration.

Abstract: Aspects of the subject disclosure relate to tonneau covers that include features that interact with each other to facilitate loading and unloading of panels linearly and with high stability. Such features can provide smooth deployment and retraction of the tonneau cover. A tonneau cover can include individual panels that interlock with each other upon deployment and disconnect from each other upon retraction to controllably cover a truck bed or other region of a vehicle, such as a truck. Tonneau covers described herein can include panels that provide reliable sealing there between. Tonneau covers described herein can include panels that provide smooth sliding across each other and along one or more rails. Tonneau covers described herein can perform such operations with minimal noise generation.

Abstract: Aspects of the subject disclosure relate to tonneau covers include spring assemblies that facilitate loading and unloading of panels linearly and with high stability. Such spring assemblies and other features of follower assemblies can provide smooth deployment and retraction of the tonneau cover. A tonneau cover can include individual panels that interlock with each other upon deployment and disconnect from each other upon retraction to controllably cover a truck bed or other region of a vehicle, such as a truck.
