Abstract

A glass chute includes main body and sealing lip, and is shaped by extrusion in length direction. The main body includes basilar part, vehicle lateral wall part and vehicle medial wall part, which are assembled along the inner circle of vehicle doorframe; the sealing lip extends towards the inner side of the main body. The basilar part and the vehicle laterial wall part, as well as the basilar part and the vehicle medial wall part are connected with each other through a distortion connection part separately. The wall thickness of the distortion connection part is more thin than that of the basilar part as well as the two side wall, the across section of the distortion connection part is basically J-shaped, so as to be provided with prescribed length in width direction. The distortion connection part is bended and distorted through folding in two angle parts of the glass chute, the basilar part can slide into the inner-cycle side smoothly and can be bended continuously without slitting or concave part.

Description

technical field [0001] The invention relates to a glass runway and its assembly structure. Background technique [0002] Typically, glass run channels are provided along the inner circumference of the vehicle door frame. Viewed from its cross-sectional direction, the glass run channel includes a main body with a U-shaped cross section, an inner sealing lip and an outer sealing lip. The main body includes a base, an inner wall extending from the base, and a The outer wall portion, the inner seal lip and the outer seal lip extend toward the inner side of the main body portion. According to the glass run channel described above, the body portion is fitted to the fitting portion (for example, the run portion) provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass are pressed by the two sealing lips, thereby creating a seal. [0003] In recent years, the glass run channel is composed of an extruded par...
