Abstract

A sealing structure for a movable window allows a movable windowpane to lie flush with the outside of the window sill frame. The vertical edges of the windowpane are provided with projecting guides which have a runner lying somewhat offset from the plane of the rest of the pane. The guide runners are supported by elastic seals such that the pane lies flush with the outer surface of the window sill frame. A vibration damper in the shape of an inverted "V" may be provided at the top of the window sill frame in order to guide the top edge of the pane into place and to prevent the pane from vibrating excessively.

Claims

1. A sealing structure for a movable window in an automotive vehicle having a window sill frame which includes two substantially parallel vertical sash portions, an upper, horizontal sash portion and a slanted sash portion inclined to said upper, horizontal sash portion, said upper, horizontal sash portion being at one end connected to one of said two vertical sash portions and being at the other end connected to an upper end of said slanted sash portion, the other of said two vertical sash portions being connected at an upper end thereof to said slanted sash portion, the sealing structure comprising:

(a) a pane having two parallel vertical edges, the separation of which corresponds to the separation of the vertical sash portions, an upper, horizontal edge, the configuration of which corresponds to that of the upper, horizontal sash portion, and a slanted edge, the configuration of which corresponds to that of the slanted sash portion, the pane being adapted to be moved parallel to the direction in which the vertical sash portions extend;

(b) guide means secured to the inward surface of said pane near said vertical edges and having a runner projecting beyond said vertical edges and lying in a plane parallel to said pane and offset inwardly therefrom by a given distance;

(c) vertical sealing means disposed along the vertical sash portions for engaging said runner to retain said runner in a position offset inwardly from the outward surface of the window sill frame by the given distance;

(d) horizontal sealing means disposed along the horizontal sash portion for cushioning said horizontal edge from the horizontal sash portion;

(e) slanted sealing means disposed along the slanted sash portion for cushioning said slanted edge from the slanted sash portion; and

(f) vibration damper means disposed on the upper end of the slanted sash portion for receiving a corresponding portion of said slanted edge and for elastically damping vibrations thereof, said vibration damper means comprising outwardly and inwardly extending resilient flaps joining to form an inverted V-shaped member fixed to the slanted sash portion, said corresponding portion of said slanted edge being received by said inverted V-shaped member so as to be retained by said flaps.

2. The sealing structure of claim 1, wherein said vertical sealing means includes outward and inward lips elastically separable to allow said runner to pass therebetween in a position a distance inward from the outward surface of the vertical sash portions.

3. The sealing structure of claim 1, wherein said guide means is fixed to said pane by means of adhesive, and a layer of decorative coloration is provided between said pane and said adhesive.

4. A sealing structure as claimed in claim 1, wherein said vehicle has a rain gutter panel spaced above said horizontal sash portion, the outboard surfaces of said rain gutter panel, said horizontal sash portion and said pane being substantially flush with each other, said sealing structure further including a weather stripping having a portion thereof filling the space between said rain gutter panel and said horizontal sash portion such that the outboard surface of said weather stripping is flush with the outer surfaces of said rain gutter and said horizontal sash portion.
