Problems solved by technology

This shrinkage can negatively affect the geometry of the panel once it is molded
This negative effect has the potential to result in the panel being scrapped after molding due to substandard geometry quality, or it may result in damage to the panel during use in the vehicle due to excessive material internal stress

Embodiment Construction

[0022] figure 1 One embodiment of an open roof structure for a vehicle 1 is shown, comprising a roof opening 2 provided in a fixed roof part 3 of the vehicle. The front panel 4 and the rear panel 5 of the open roof structure are able to close and at least partially open said roof opening 2 . The front panel 4 is movable along longitudinal guides (not shown, but known per se) on opposite sides of the roof opening 2 . The rear end of the rear panel 5 can only be moved in the vertical direction, thereby freeing an opening at the rearmost side of the open roof structure. Both panels 4 and 5 can be moved manually or by drive means not shown but known per se. The cooperation between the panels 4 and 5 and the longitudinal guides can take place in any known manner and is not illustrated in detail. The invention is applicable to all types of open roof structures comprising one or more panels, in particular glass panels, but also panels made of other materials such as plastic.

Abstract

The application discloses a panel (4, 5) for use in an open roof construction for a vehicle. It comprises a substantially rectangular panel main body (6, 7), and at least one reinforcement member (8 - 11) positioned in the vicinity of at least a part of the edges of said panel main body, and firmly connected thereto by means of a plastic part (12) molded in a molding process to said panel main body and said reinforcement member. A provision (14, 15) is made for locally at least reducing adherence of plastic material to said reinforcement member and / or said panel main body during molding. There is also disclosed a method of manufacturing the panel.

Description

technical field [0001] The present invention relates to a panel for use in the construction of an open roof for a vehicle, the panel comprising a generally rectangular panel body and at least one reinforcing member located near at least a portion of the edge of said panel body and firmly connected thereto . Background technique [0002] Currently, reinforcement members are attached to the panels by plastic parts that are molded in during the molding process. The connection between stiffening member and panel produced by this plastic part is very strong. During and shortly after the molding process, the material of the plastic part will shrink. The amount of shrinkage depends on the local volume concentration of the plastic material, whereby a large amount of material produces a high shrinkage at the ends of these materials. This shrinkage can negatively affect the geometry of the panels once they are molded. This negative impact has the potential to lead to rejection of ...
