JP 2005-153650 A

As described above, for example, when two fixed glasses (fitting glass) such as a windshield and a roof glass are arranged to face each other, the appearance quality deteriorates if the distance between the end portions of each glass is not uniform. And the commercial value of a vehicle will be impaired.
In general, the windshield is set (positioned) by inserting engagement protrusions into guide holes formed in the front frame constituting the front portion of the roof frame. In addition, the roof glass is set with an attachment reference by inserting an engaging protrusion into a guide hole formed in a side frame constituting a side portion of the roof frame. However, when joining the front frame and the side frame by spot welding, it is inevitable that a certain amount of error will occur in the positional relationship of each guide hole due to the joining error. It was necessary to adjust the interval one by one.
The subject of this invention is providing the glass mounting structure for vehicles which is excellent in external appearance quality and favorable workability | operativity.

The present invention solves the above-described problems by the following means.
According to a first aspect of the present invention, there is provided a first glass fixed to the vehicle body, a second glass disposed adjacent to the first glass and fixed to the vehicle body, and protruding from the first glass. Provided in the vicinity of the boundary between the first glass and the second glass, the second engaging means provided protruding from the second glass, A vehicle body side member formed integrally with a first engaged means that engages with the first engaging means and a second engaged means that engages with the second engaging means. It is the glass mounting structure for vehicles provided with these.
Here, the engaging means is typically a protrusion fixed to the back surface of the glass, and the engaged means is typically a guide hole formed in the vehicle body side member.

  According to a second aspect of the present invention, the first glass is a windshield, the second glass is a roof glass extending rearward from the vicinity of the upper end of the windshield, and the roof glass is substantially at the front end. The front frame is supported by a front frame disposed along a side frame and a side frame disposed substantially along a side edge, and the vehicle body side member is formed such that both end portions wrap around the side edge of the roof glass. And a stiffening member fixed to a structural member of the A pillar or roof side portion of the vehicle body and connected to a side end portion of the front frame and a front end portion of the side frame, respectively. The glass mounting structure for a vehicle according to claim 1.

According to the present invention, the following effects can be obtained.
(1) Engage the first engaging means of the first glass and the second engaging means of the second glass with the engaged means provided on the vehicle body side member formed integrally. As a result, the gap between the glasses is not affected by the joining error during vehicle body assembly, such as spot welding, which improves the appearance quality and simplifies complicated position adjustment work and improves workability. can do.
(2) Both the windshield and the roof glass are positioned on the front frame provided over the entire width of the roof glass, and the stiffening member provided on the front frame and the side frame from the A pillar or roof side structural member is provided. Thus, the strength of the joint portion between the front frame and the side frame can be improved, and even when these joint portions are provided at the side end portions of the roof frame, it is possible to prevent adverse effects on the side collision performance of the vehicle.
