Glass guide seal for the upper side of a window opening of a motor vehicle

The glass guide seal (1) is intended for the upper side of a window opening (2) of a motor vehicle, in which upper side there is provided a bearing structure (3) shaped like an inverted channel, which defines a downwardly open recess or receptacle (6), between two opposite side walls (4, 5). The seal (1) comprises a profile member (7) the cross section of which has two anchoring terminal portions (8, 9) intended to be connected to the lower edges of the side walls (4, 5) of the bearing structure (3), and an intermediate portion (10), likewise shaped as an inverted channel, intended to be positioned in the recess or receptacle (6) and having a terminal buffer wall (11) the ends of which are joined to respective, opposite, side walls (12, 13). Between these side walls (12, 13) a movable glass window pane (14) can extend, the upper edge (14a) of which in the nominal closed position extends adjacent to the buffer wall (11). The side walls (12, 13) of the intermediate portion (10) of the seal (1) have respective portions or parts of reduced cross section (12a, 13a) which are resiliently extensible like springs. The arrangement is such that when, in use, the upper edge (14a) of the glass window pane (14) goes beyond the nominal closed position and urges the terminal buffering wall (11) upwards, the portions or parts of reduced cross section (12a, 13a) allow an increased resilient extension of the intermediate portion (10) of the seal (1).
