Abstract

A door window glass run channel for an automotive vehicle comprises an enlarged portion (6) protruding from a base having an essentially "U" shaped window guide channel (1) for guiding a window into the "U" shaped window guide channel (1). <IMAGE>

Description

SPECIFICATION Automotive vehicle door window glass run channel The present invention relates to a door window glass run channel for an automotive vehicle.

There is a conventional door window glass run channel of this kind shown in Fig. 4. That is, the "U"-shaped glass run channel 1 has a base 1 a and is positioned within a sash frame 3 forming an upper part of a door 2, wherein inwardly oriented lips 1 b, 1 b' extending from the edges of the inner sides of the base 1 a are adapted to guide the door window 4. 5 designates a door weatherstrip embraced by the sash frame in a manner similar to the channel 1.However, with such a conventional channel, because the amount of projection "a" from that portion 1 c of the root of each of the lips 1 b, 1 b' which seats on the door sash frame 3 is small and thus a width of a guide "b" for the door window is narrow, there occur problems that the window 4 deviates from the width "b" of the window inserting guide during closing movement of the window, to make it impossible to move the window to its closed position, which may occur when the door window sways laterally upon closing the window 4 or when the window is deviated laterally due te rnanufacturing tolerance or when the window 4 is sucked to sway laterally outwardly due to a vacuum created during high speed running of the vehicle.

The present invention has been effected on the recognition of this conventional problem and has solved the above mentioned problem by enlarging and protruding a portion of a seat portion of a glass run channel from the general surface thereof.

According to the present invention, a width of a guide has been substantially increased by forming at least one enlarged portion protruding outwardly from a seat portion of a glass run channel.

Therefore, the possibility that the closing operation is disabled due to the deviation of the door window is eliminated.

In the accompanying drawings: Fig. 1 is a side elevation of a vehicle door in which the present invention is embodied; Fig. 2 is a cross-section through the line 11-Il of Fig. 1; Fig. 3 is a side elevation of Fig. 2 as viewed from the left in the drawing; and Fig. 4 is a view similar to Fig. 2 illustrating the prior art explained before.

Figs. 1 to 3 are views illustrating an embodiment according to the present invention.

The same reference numerals used for explaining the conventional door window glass run channel are used to designate counterparts and the explanation thereof is omitted for the sake of simplicity.

Explaining firstly the construction, that part of a seat portion 1 C of a glass run channel 1 which is disposed in the proximity of an upper portion of a front piilar (not shown) is enlarged and protrudes outwardly from the general surface at one or two locations, and this enlarged and protruding portion 6 has a guide surface 6a formed on the inner side thereof to guide the door glass 4. The area designated by H includes this enlarged portion 6 of the channel 1 and those ends of it which include the general portion are formed by molding and are adhered to the ends of the general portion which is formed by extrusion. Since the general portion has the guide surface 6a formed thereon, it is necessary to provide an appropriate rigidity thereto.To achieve this, the enlarged portion 6 is formed with increased hardness and/or a core metal 7 of a steel plate or the like inserted thereinto, as shown in Fig. 2.

With this construction, the amount of protrusion A of the seat portion 1 c of the glass run channel 1 increases partially and the width B of the guide surface 6a of the inserting guide for the door window 4 increases correspondingly, so that the deviation of the door window from the abovementioned guide surface 6 does not take place, even if there occurs a swaying movement of the door window 4 when it is sucked outwardly due to a vacuum created around the periphery of the door window during closing movement thereof, thus ensuring a smooth window closing movement. In this instance, the enlarged protruding portion 6 does not collapse because of its rigidity.

As described, according to the present invention, a width of the guide surface has been increased by partially enlarging and protruding a seat portion, a possibility that the closing operation is disabled due to the deviation of the door window has been eliminated.

1. A vehicle door and window glass run channel therefor, comprising: a) a sash frame forming the upper part of the vehicle door: b) a base having an essentially "U" shaped window guide channel and positioned within said sash frame; and c) an enlarged portion protruding from said base for guiding the window into said "U" shaped guide channel.

2. A vehicle door and window glass run channel as claimed in claim 1, wherein said base has inwardly oriented lips adapted to interpose and guide the window.

3. A vehicle door and window glass run channel as claimed in claim 1, including a metal reinforcement to hold said enlarged portion in its shape.

4. A vehicle door and window glass run channel as claimed in claim 1, wherein said enlarged portion is a hardened rubber or the like.
