The disclosure relates generally to window subassemblies. In particular aspects, the disclosure relates to vehicles and vehicle window subassemblies for bonded installation of an initial window subassembly and subsequent roped installation of a replacement window subassembly.
Vehicle window subassemblies, such as for heavy truck vehicles, require initial installation and occasionally require subsequent replacement (e.g., due to an accident, being hit by a rock, etc.). For initial installation, a bonded window subassembly is generally preferred, as factory installation is easier and cheaper with direct bonding. However, for subsequent replacement window installation, a roped window subassembly is generally preferred for ease of aftermarket replacement. However, a vehicle body (e.g., body in white (BIW)) is typically configured only for one of these types of window subassemblies. Installing an aftermarket roped window subassembly on a vehicle body that previously had a bonded window subassembly is typically difficult as the residual bonding agent obstructs the sealing surface and compromises the seal. Further, removal of the bonding agent (e.g., by chemical means, mechanical means, etc.) can damage the paint, lead to rust, etc.
According to an aspect of the disclosure, a window subassembly for a vehicle includes a window, a bonding agent, and a bonded window trim. The bonding agent is attached to an internal surface of the window and proximate to an edge of the window. The bonding agent is configured to attach the window to a window mount of a vehicle. The bonded window trim is engaged with the edge of the window, and has an external portion contacting an external surface of the window and an internal portion contacting the internal surface of the window. The bonded window trim is configured to, upon attachment of the window to the window mount, preserve a replacement space of the window mount for roped installation of a replacement window by keeping the space clear of bonding agent.
In certain embodiments, the bonded window trim includes a bonded trim lip extending away from the internal surface of the window to contact the window mount before the bonding agent spreads to the replacement space upon attachment of the window to the window mount.
In certain embodiments, the bonded window trim comprises a bonded trim lip configured to deform upon attachment of the window to the window mount to preserve the replacement space.
In certain embodiments, the bonded trim lip is resilient and extends away from the internal surface of the window.
In certain embodiments, the internal portion of the bonded window trim includes a spacing length configured to preserve the replacement space.
In certain embodiments, the bonded window trim is configured to preserve the replacement space having a length between 5-15 mm.
In certain embodiments, the bonding agent comprises a pyramidal shape having a base between 5-15 mm and a height between 5-15 mm.
According to another aspect of the disclosure, a window subassembly for a vehicle includes a window and a roped window trim. The roped window trim is engaged with an edge of the window. The roped window trim has an external portion contacting an external surface of the window, an intermediate portion contacting an internal surface of the window, and an internal portion configured to contact an internal surface of a window mount. The roped window trim is configured to, upon attachment of the window to the window mount, create a seal in a replacement space of the window mount and not create a seal in a bonding space of the window mount.
In certain embodiments, the roped window trim includes a roped trim lip extending away from the internal surface of the window to contact the window mount to create a seal between the roped window trim and the window mount upon attachment of the window to the window mount.
In certain embodiments, the roped window trim includes a roped trim lip configured to deform upon attachment of the window to the window mount to create a seal between the roped window trim and the window mount.
In certain embodiments, the roped trim lip is resilient and extends away from the internal surface of the window.
In certain embodiments, the roped window trim defines a recess between the roped trim lip and an inward edge of the intermediate portion to create a gap between the window mount and the intermediate portion of the roped window trim upon attachment of the window to the window mount.
In certain embodiments, the gap is larger than 1 mm to avoid contact with any residual bonding agent, the residual bonding agent being less than 1 mm thick.
In certain embodiments, the roped window trim is configured to, upon attachment of the window to the window mount, create a seal in a replacement space of the window mount and not create a seal in a bonding space of the window mount, wherein the replacement space is outward from the bonding space.
In certain embodiments, the replacement space is between 5-15 mm wide.
According to another aspect of the disclosure, a vehicle includes a vehicle body including a window mount with a flange. The flange includes a bonding space and a replacement space. The bonding space is configured for bonded installation of a window, and the replacement space is configured for roped installation of a replacement window.
In certain embodiments, the flange has a length between 25-35 mm.
In certain embodiments, the bonding space and the replacement space each have a length between 5-15 mm.
In certain embodiments, the vehicle further includes a window subassembly. The window subassembly includes the window, a bonding agent, and a bonded window trim.

The window subassembly 104 includes a window 110 and a trim 112 (may also be referred to as a seal member, rubber seal, etc.) around a peripheral edge of the window 110. The trim 112 is configured to form a seal (e.g., watertight) around a periphery of the window 110 between the window 110 and the window mount 106 to prevent water from entering the interior of the vehicle body 102.
As discussed in more detail below, there are generally two types of window subassemblies 104. One type is a bonded window subassembly which is bonded to the window mount 106 by a bonding agent, which is generally preferred for initial factory installation. Another type is a roped window assembly, which is mounted to the window mount 106 by mechanical application of the trim 112, which is generally preferred for ease of aftermarket replacement. The vehicle body 102 and/or window subassembly 104 are configured to allow for initial application of a bonded window subassembly and subsequent replacement by a roped window subassembly, while also avoiding any residual bonding agent that may obstruct the sealing surface and/or compromise the seal.
The flange 208 includes a bonding space B and a replacement space R. In certain embodiments, the bonding space B is proximate to the inward peripheral edge 210, and the replacement space R is proximate to the intermediate wall 206. The bonding space B is configured for bonded installation of a window, and the replacement space R is configured for roped installation of a replacement window. In certain embodiments, the flange 208 has a length between 25-35 mm. In certain embodiments, the bonding space B and the replacement space R each have a length between 5-15 mm.
The bonded window subassembly 200 includes a bonded window 212 having an external surface 214A and an internal surface 214B. In certain embodiments, the bonded window 212 includes a peripheral edge 216 and a groove 218 defined by the peripheral edge 216 and at least partially extending around the bonded window 212. The bonded window subassembly 200 further includes a bonding agent 220 at the internal surface 214B and proximate to the peripheral edge 216 of the bonded window 212. The bonding agent 220 is configured to attach the bonded window 212 to the window mount 106 of the vehicle 100.
The bonded window subassembly 200 further includes a bonded window trim 222 engaged with and extending around the peripheral edge 216 of the bonded window 212. The bonded window trim 222 is configured to, upon attachment of the bonded window 212 to the window mount 106, preserve (e.g., protect) a replacement space of the window mount 106 from the bonding agent 220 for roped installation of a replacement window.
The bonded window trim 222 includes an external portion 224 contacting the external surface 214A of the bonded window 212, an internal portion 226 contacting the internal surface 214B of the bonded window 212, and an outer wall portion 228 contacting the peripheral edge 216 of the bonded window 212. The external portion 224 and the internal portion 226 are connected to one another by the outer wall portion 228. The bonded window 212 is positioned between the external portion 224 and the internal portion 226. Further, the outer wall portion 228 includes an inwardly extending ridge 230 positioned within the groove 218 to further secure the bonded window trim 222 to the bonded window 212.
In certain embodiments, the bonded window trim 222 further includes a flap 232 outwardly extending over the intermediate wall 206 of the window mount 106 and configured to contact the external surface 202A of the vehicle body 102 to provide a seamless aesthetic. The bonded window trim 222 further includes a bonded trim lip 234 extending away from the internal surface 214B of the bonded window 212 (e.g., downwardly extending) and configured to contact the window mount 106. The bonded trim lip 234 is at a bottom of the internal portion 226 and at an internal edge 236 of the internal portion 226 of the bonded window trim 222.
The bonded trim lip 234 extends away from the internal surface 214B of the bonded window 212 and is configured to contact the window mount 106 before the bonding agent 220 spreads to the replacement space R upon attachment of the bonded window 212 to the window mount 106. Accordingly, the bonded trim lip 234 forms an initial dam that prevents the bonding agent 220 from spreading underneath the bonded window trim 222 (i.e., between the bonded window trim 222 and the flange 208).
The bonded trim lip 234 and/or internal portion 226 preserve the replacement space R from the bonding agent 220. In certain embodiments, the internal portion 226 of the bonded window trim 222 has a spacing length S configured to preserve the replacement space R. In certain embodiments, the spacing length S includes the bonded trim lip 234. In other embodiments, the spacing length S excludes the bonded trim lip 234. In certain embodiments, the spacing length S of the internal portion is less than the replacement space R of the flange 208. In certain embodiments, the bonded window trim 222 is configured to preserve the replacement space R having a length between 5-15 mm wide. This replacement space R provides a sealing surface for a subsequent roped window subassembly.
The roped window trim 410 includes an external portion 412 contacting the external surface 404A of the roped window 402, an intermediate portion 414 contacting the internal surface 404B of the roped window 402, an outer wall portion 416 contacting the peripheral edge 406 of the roped window 402, and an internal portion 418 configured to contact the internal surface 202B of the flange 208 of the window mount. The external portion 412 and the intermediate portion 414 are connected to one another by the outer wall portion 416 at an outer edge of the intermediate portion 414 proximate to the peripheral edge 406. The roped window 402 is positioned between the external portion 412 and the intermediate portion 414. Further, the outer wall portion 416 includes an inwardly extending ridge 420 positioned within the groove 408 to further secure the roped window trim 410 to the roped window 402.
In certain embodiments, the roped window trim 410 further includes a flap 422 outwardly extending over the intermediate wall 206 of the window mount 106 and configured to contact the external surface 202A of the vehicle body 102 to provide a seamless aesthetic.
The roped window trim 410 further includes a roped trim lip 424 (may also be referred to as a seal lip) extending away from the internal surface 404B of the roped window 402 (e.g., downwardly extending) and configured to contact the window mount 106. The roped trim lip 424 is at a bottom of the internal portion 418 and proximate to the outer wall portion 416.
In certain embodiments, the roped window trim 410 further includes a biasing skirt 425 (may also be referred to as a biasing lip) extending away from a peripheral edge 406 of the roped window 402 and configured to contact the intermediate wall 206. The biasing skirt 425 provides stability to the roped window 402 and helps center the roped window 402 in the window mount 106.
The intermediate portion 414 and the internal portion 418 are connected to one another at an inner edge of the intermediate portion 414. The internal portion 418 hooks upwardly toward the peripheral edge 406 of the roped window 402. Further, in certain embodiments, the roped window subassembly 400 includes rope 426 positioned between the internal portion 418 and the intermediate portion 414.
The roped trim lip 424 forms a seal against the flange 208 in the replacement space R. The replacement space R does not include any of the bonding agent 220. In other words, the roped window trim 410 includes the roped trim lip 424 extending away from the internal surface 202B of the roped window 402 to contact the window mount 106 to create a seal between the roped window trim 410 and the window mount 106 upon attachment of the window to the window mount 106. Further, the roped trim lip 424 is configured to deform upon attachment of the roped window 402 to the window mount 106 to create a seal between the roped window trim 410 and the window mount 106. Accordingly, for example, fluid (e.g., liquid, air, water, etc.) cannot flow past the seal into an interior of the vehicle 100.
The roped window trim 410 defines a recess 430 between the roped trim lip 424 and an inward edge 432 of the intermediate portion 414 to create a gap 434 between the window mount 106 and the intermediate portion 414 of the roped window trim 410 upon attachment of the roped window 402 to the window mount 106. In particular, the roped window trim 410 forms a gap 434 between the intermediate portion 414 and the bonding agent 220. Thus, the roped window trim 410 is configured to clear the residual bonding agent 220 without interference. In certain embodiments, the gap 434 is larger than 1 mm to avoid contact with any residual bonding agent 220 (e.g., less than 1 mm thick). Avoiding contact with the bonding agent 220 prevents potential problems in forming the seal in the replacement space R.
The roped window trim 410 is configured to, upon attachment of the roped window 402 to the window mount 106, create a seal in the replacement space R of the window mount 106 and not create a seal in a bonding space B of the window mount 106. In certain embodiments, the replacement space R is outward from the bonding space B.
Those skilled in the art will recognize improvements and modifications to the preferred embodiments of the present disclosure. All such improvements and modifications are considered within the scope of the concepts disclosed herein and the claims that follow.
