Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a front header structure of an open car with an open roof portion.

[Conventional technology]

In a convertible car with an open roof, a front header is provided along the upper edge of the windshield in the vehicle width direction, consisting of a front header upper and a front header lower that are joined to each other in a closed section. , when the roof is installed, the leading edge of the roof is fixed to the above-mentioned front header. In order to fix the front edge of the roof in this way, for example, in US Pat. A structure is disclosed in which a front header-side locking member having a roof-side locking member is attached, and a hook portion of the roof-side locking member is engaged with and fixed to the front header-side locking member.

The front header as described above, and both left and right ends thereof, are respectively connected to the upper ends of each front pillar provided along both side edges of the window shield. Each of these front pillars is formed by joining a front pillar outer and a front pillar inner to each other in a closed cross-sectional shape. Furthermore, conventionally, in order to increase the strength and rigidity of the front header, a reinforcement has been used between the front header upper and the front header lower.

[The problem that the idea aims to solve]

However, in the conventional open car front header structure described above, the front header side lock member is attached only to the front header, so the mounting rigidity of the front header side lock member tends to be low.For this reason, the load applied from the roof is transferred to the front header. The problem is that it is difficult to ensure that the lock is received by the side lock member.

Further, the error in the mounting position of the front header side locking member with respect to the entire vehicle body is an accumulation of the dimensional error and mounting error of the front header and the dimensional error and mounting error of the front pillar. Furthermore, the amount of displacement of the mounting position of the front header side locking member due to the load applied to the front header from the roof is a combination of the amount of deformation of the front header and the amount of deformation of the front pillar. Errors and displacements tend to become large, and there are also problems in that it is difficult to increase the accuracy of the mounting position of the front header side lock member.

[Means to solve the problem]

In order to solve the above-mentioned problems, the front header structure of a convertible car according to the present invention has a pair of front pillars each formed with a closed cross section by a front pillar outer and a front pillar inner, along both side edges of the windshield. A front header is provided along the upper edge of the windshield, and the front header is formed into a closed section by a front header upper and a front header lower. In the front header structure of a convertible car that is connected to the vehicle while the roof portion is open, a corner portion extending toward the center in the vehicle width direction is provided at the upper end of each of the front pillar inners, and these corner portions extend toward the front. They are joined to each other on the end side of the lower part, and a locking member is attached to the surface on the inside of the vehicle at these overlapping joint parts to fix the area near the leading edge of the roof attached to the roof part. It is a feature.

[Effect]

In the above configuration, the locking member that fixes the vicinity of the front edge of the roof is attached to the overlapping joint portion of the corner portion of the front pillar inner on the end side of the front header lower.
The mounting rigidity increases.

Further, since the lock member is directly attached to the upper end of the front pillar, the error in the attachment position of the lock member with respect to the entire vehicle body is determined mainly by the dimensional error and attachment error of the front pillar. Further, the amount of displacement of the mounting position of the front header-side locking member due to the load applied to the front header from the roof, etc. is mainly determined only by the amount of deformation of the front pillar. Therefore, errors and displacements in the mounting position of the locking member are reduced, and as a result, the accuracy of the mounting position of the locking member is improved.

The mounting rigidity of the striker 31 is kept sufficiently high. Therefore, for example, a load applied from the roof 10 when the vehicle is running is transmitted via the top block assembly 51 and the striker 31, and is reliably received by the front pillar 11 and the front header 21.

Further, the error in the mounting position of the striker 31 with respect to the vehicle body 1 is mainly determined only by the dimensional error and the mounting error of the front pillar 11. Therefore, the error in the attachment position of the striker 31 can be suppressed to the same level as when the striker 31 is attached directly to the front pillar 11.

Furthermore, the amount of displacement of the mounting position of the striker 31 with respect to the vehicle body 1 is mainly determined by
It is determined only by the displacement amount of 1. Therefore, the amount of displacement of the mounting position of the striker 31 can also be suppressed to the same level as when the striker 31 is directly mounted to the front pillar 11.

Therefore, by attaching the striker 31 to the overlapping portion of the front pillar inner 13 and the front header lower 23, the attachment rigidity of the striker 31 is increased, and
Mounting position accuracy can be increased.

[Effect of idea]

As described above, in the front header structure of a convertible car according to the present invention, a corner portion extending toward the center in the vehicle width direction is provided at the upper end of each front pillar inner, and these corner portions are connected to the front header floor. They are joined together on the end sides, and a locking member for fixing the vicinity of the front edge of the roof attached to the roof portion is attached to the surface of the overlapping joint portion on the inside side of the vehicle.

As a result, the locking member that fixes the vicinity of the front edge of the roof is attached to the overlapping part of the front header lower and the front pillar inner, so the mounting rigidity of the locking member can be increased, and the load from the roof can be increased. The load can be reliably received.

In addition, since the lock member is attached directly to the upper end of the front pillar, errors in the attachment position and displacement of the lock member relative to the entire vehicle body are mainly caused by dimensional errors, installation errors, and deformation of the front pillar. Since it is determined only by the amount, it is possible to improve the accuracy of the mounting position of the lock member.
