Abstract
A window assembly for a motor vehicle includes a sheet and a sealing element for a fixed window to be secured to the edge portion of a section of the vehicle body. The sealing element features a bonding portion, which is bonded to the inside of the sheet, and includes a sealing lip projecting from the bonding portion, which can be brought into contact with the edge portion of the vehicle body section. To facilitate repainting of the edge portion of the vehicle body section the sealing lip, over its length, features at least a first and second layer, which are arranged one over the other and are tightly bonded to one another. The first layer forms an external surface layer and exhibits a higher temperature resistance than the second layer.
Claims9
A window assembly for a motor vehicle comprising:
- an automotive window, and
- a sealing element for the window to be bonded to an edge portion of a window aperture,
- wherein the sealing element features a mounting portion, which is adapted to be bonded to the inside of the window,
- wherein the sealing element includes a sealing lip, projecting from the mounting portion, which can be brought in contact with an edge of the window aperture,
- wherein, over its length, the sealing lip has at least a first layer and a second layer which are placed adjacent to each other and which are tightly bonded to one another,
- wherein the first layer forms an external surface layer and features a higher resistance to temperature than the second layer, which underlies the first layer,
- wherein the mounting portion defines a bearing formed of at least two layers of differing hardness arranged adjacent to each other,
- wherein a lower layer of the bearing is softer than an upper, overlying layer of the bearing,
