A bowed spring [0 bears against at the lower end on a pivot to the bracket arm the inside of the segmental rack to hold it in 4 and held along its upperreaches to the face of engagementwith the pinion 6. The spring is the pinion by the spring I 0. The comparison of Figs. 1 and 2 indicates the path of the rack and also the movement of the sliding quarter panel. It will be noticed that the arrangement of the parts allows the curved rack to exert a straight line push on the sliding window. That is, the portion 5a on the rack 5 pivots with respect to the carrying arm 5 and exerts a continuous force parallel to the track 26, thereby reducing to a minimum any tendency of the glass frame to bind in its guideways.

The window is guided in its fore and aft movements by a T track 26 that is welded to the turned in portion of the inner panel I6. This T track is formed by folded metal. The head of this T track engages in a channel formed by the folded over angular guide strip 21 which is welded to the bottom of the sash channel 2.

I claim:

1.. The combination with a body having a quarter window opening provided with a guide for fore and aft sliding movements, a sliding window panel arranged to move fore and aft in said guide and a window regulator in the form of a driving pinion and a segmental rack arranged to travel in a curvilinear path and pivoted to the window panel and engaging with the pinion for sliding the window panel fore and aft, said rack in passing forward past the pinion retreating up along the forward edge of the window opening.

2. The combination with a body having a quarter window opening provided with a guide for fore and aft sliding movements, a sliding window panel arranged to move fore and aft in said guide and a window regulator in the form .of a driving pinion, a segmental rack arranged to travel in a curvilinear path and pivoted to the window panel and engaging with the pinion for sliding the window panel fore and aft and a spring member bearing against the side of the rack opposite the rack teeth for holding the rack into engagement with the pinion, said rack in passing forward past the pinion retreating up along the forward edge of the window opening.

3. The combination with a body having a quarter window opening provided with a guide for fore and aft sliding movements, a sliding window panel arranged to more fore and aft in said guide and a window regulator located forward of the window opening and near but above the bottom thereof comprising a driving pinion and having a segmental rack arranged to travel in a curvilinear path and pivoted at the bottom and the forward end of the sliding panel and engaging with the driving pinion, said rack in passing forward past the pinion retreating up along the forward edge of the window opening.

4. The combination of a body having a door opening and provided with a rear quarter panel having a window opening in which the forward boundary of the window opening slopes rearwardly from top to bottom providing an; angular space between the window opening at the bottom thereof and the door opening, a sliding panel guided for fore and aft sliding movement in said window opening, a window regulator located in said space near the bottom of the window opening and between the window opening and the door opening comprising a driving pinion and a segmental rack pivoted at the bottom of the window and held in engagement with the teeth of the driving pinion, said rack in passing forward past the pinion retreating up along the forward edge of the window opening.

5. The combination of a body having a door opening and provided with a rear quarter panel having a window opening in which the forward boundary of the window opening slopes rearwardly from top to bottom providing an angular space between the window opening at the bottom thereof and the door opening, a sliding panel guided for fore and aft sliding movement in said Window opening and a window regulator located in said space near the bottom of the window opening and between the window opening and the door opening, said regulator comprising a driving pinion, a curved segmental rack pivoted at the bottom of the window and aspring anchored on the window regulator and bearing against the back of the segmental rack for holding the same yieldingly in engagement with the teeth of the pinion, said curved segmental rack retreating,

when moving forwardly, up .into said angular space.

6. The combination of a body having a door opening and provided with a rear quarter panel having a window opening in which the forward boundary of the window opening slopes rearwardly from top to bottom providing an angular space between the window opening at the bottom thereof and the door opening, a sliding panel guided for fore and aft sliding movement in said window opening and a window regulator located in said space near the bottom of the window opening and between the window opening and the door opening, said regulator comprising a driving pinion, a segmental rack pivoted at the bottom of the window, one or more lugs on said window regulator, and a spring anchored on said lugs and bearing against the back of the segmental rack for holding the same yieldingly in engagement with the teeth of the pinion, said lugs serving also to hold the rack in engagement with the teeth of the pinion in case of breakage of said spring.

'7. The combination with a body provided with a rear quarter window opening formed by an inner panel and an outer panel having turned in portions and a T track welded to the turned in portion of the inner panel, a sliding panel supported in a sash channel and a guide strip secured to the bottom of the sash channel and fitting over the top of the T and having a sliding engagement with the track.
