Abstract: A back support for a chair includes a cover configured to be coupled to opposing sides of a chair frame. A strap is connected to the cover. A sled having a central portion is coupled to the strap, the sled is configured to pivot with respect to the chair frame and provide support to a user's back. The cover is configured to moveably connect to the chair frame between a low position and a high position. The sled is configured to pivot as the cover moves between the low position and the high position so that the central portion of the sled is substantially parallel to at least a portion of a membrane connected to the frame between the low position and the high position.

Abstract: An electrification system for use with an article slidably supported on a track within a vehicle is provided. The electrification system comprises a conductor assembly including a positive conductive interface supported parallel and adjacent to a negative conductive interface. The conductor assembly is configured to extend substantially the length of the track. The electrification system further comprises a contact assembly including a positive contact in electrical communication with the positive conductive interface and a negative contact in electrical communication with the negative conductive interface. The contact assembly is configured to be fixed relative to the article. The contact assembly remains in electrical communication with the conductor assembly as the article is selectively moved along the track to provide continuous electrical power to the article as the article is moved.
