Window regulator mechanism

摘要

A window regulator mechanism for raising and lowering a window that slides up and down in a hollow closure. The window regulator mechanism includes a base plate that supports a tape drive that pulls the window up and pulls the window down. The tape wraps around upper and lower rollers that rotate on axes that are substantially parallel to the length of the closure. Two slack take-up devices for the tape are disclosed. An alternate window regulator mechanism drives the tape with conformation and does not need any slack take-up.
