Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a top ceiling provided on the passenger compartment side of a roof rail inner extending in the front-rear direction of a vehicle, and a striker for engaging a locking device at the upper front end of a rear door in a double door structure. The present invention relates to a vehicle interior material mounting structure that is fastened to a roof rail inner.

[0002]

2. Description of the Related Art Conventionally, a double door structure has a front door whose front end is supported by a front hinge so that it can be opened and closed, and a rear door whose rear end is supported by a rear door hinge so that it can be opened and closed. ing.

In the case of the door having the double door structure and the center pillar-less structure on the vehicle body side, a lock device is provided on the upper front end of the rear door, and the roof rail inner is latched by the lock device at a position corresponding to the lock device. It is common to provide a striker that engages with the body side striker to engage the door side latch (Japanese Patent Laid-Open No. 2001-105864).

The striker described above is constructed so that it can be adjusted so as to properly maintain the engaged state with the latch of the lock device. However, the top sealing formed of a member such as urethane is used to cover the roof panel from the passenger compartment or the striker. In the case of surrounding the periphery, it is necessary to remove the top ceiling when adjusting the striker, and there is a problem that the striker adjusting operation becomes complicated.

[0005]

SUMMARY OF THE INVENTION The present invention provides a garnish, which is a member separate from the top ceiling, at a position corresponding to a striker, and the garnish is detachably attached to a bracket provided on a roof rail inner. An object of the present invention is to provide a vehicle interior material mounting structure capable of adjusting the engagement position of the striker by removing only the garnish without removing any of the above-mentioned top sealing when adjusting the striker.

[0006]

The interior material mounting structure for an automobile according to the present invention is provided with a top ceiling on the interior side of a roof rail inner extending in the front-rear direction of the vehicle and at the top of the front end of the rear door of the double door structure. An interior material mounting structure for an automobile, wherein a striker engaging a locking device is fastened to the roof rail inner, wherein the striker is fastened to the roof rail inner so that a mounting position can be adjusted from a lower side, and a position corresponding to the striker. Is provided with a garnish formed of a member different from the top ceiling, and the garnish is detachably attached to a bracket provided on the roof rail inner.

According to the above structure, the position corresponding to the striker (that is, the position below the striker from the passenger compartment side)
In addition, by providing a garnish separate from the top ceiling and attaching this garnish to the bracket provided on the roof rail inner so that it can be attached and detached without removing the top ceiling when adjusting the striker.
If only the garnish is removed, the engagement position between the latch of the lock device on the door side and the striker on the body side can be easily adjusted from below, and the striker adjustment work can be smoothed.

In one embodiment of the present invention, the bracket is provided with a support portion for supporting a curtain airbag arranged outside the top ceiling. According to the above configuration, the curtain airbag can be also supported by the bracket for detachably attaching the garnish.

In one embodiment of the present invention, the bracket is provided with a guide surface for expanding and directing the bag member of the curtain airbag toward the interior of the vehicle. According to the above configuration, since the bag member is deployed and oriented in the vehicle interior direction by the guide surface of the bracket, it is possible to prevent the bag member from entering the striker side when the airbag is activated.

In one embodiment of the present invention, the bracket supports a head impact absorbing member arranged outside the top ceiling. The head impact absorbing member having the above-described configuration may be configured by a so-called resin rib in which resin plates are combined in a lattice shape, or may be configured by low-resilience polyurethane foam.

According to the above structure, the head impact absorbing member can also be supported by the bracket for mounting the garnish. Further, when the portion that supports the head impact absorbing member is set as the load receiving surface, movement of the head impact absorbing member to the outside of the vehicle is restricted by this load receiving surface, and the impact absorbing rate by the absorbing member is improved. It is also possible.

In one embodiment of the present invention, the bracket is provided with a mounting portion for mounting the head impact absorbing member. According to the above configuration, the head impact absorbing member can be easily attached to the attaching portion of the bracket, and the bracket can prevent the head impact absorbing member from moving to the outside of the vehicle.

In one embodiment of the present invention, the lower end of the bracket is disposed close to the top ceiling, and a restricting portion for restricting the upward movement of the top sealing is formed at the tip of the lower end. According to the above configuration, since the above-described restricting portion restricts the upward movement of the top sealing, it is possible to improve the texture.

In one embodiment of the present invention, the restricting portion is formed by a folded-back portion in which a tip portion of a lower end of the bracket is folded back toward the outside of the vehicle. According to the above configuration,
Since the regulation portion is configured by the folded-back portion that is folded back to the outside of the vehicle, the movement of the top sealing can be regulated by the folded-back portion without hindering the deployment of the bag member when the curtain airbag is operated, This is effective when forming the above-mentioned guide surface on the upper part of the folded portion.

In one embodiment of the present invention, the bracket is attached to the roof rail inner at least at two points in the vehicle front-rear direction, one of the attaching portions is inserted and fixed to the roof rail inner, and the other of the attaching portions is an attaching member. It is fixed.

According to the above construction, one of the brackets has the insertion fixing structure and the other has the tightening fixing structure with the mounting members such as bolts and nuts. Therefore, the bracket can be assembled while the number of parts is reduced. It is possible to improve the property.

You can regulate movement to.

Further, the lower end of the bracket 31 is disposed in the vicinity of the top ceiling 45, and a restricting portion (see the folded-back portion 46) for restricting the upward movement of the top ceiling 45 is formed at the tip end of the lower end. is there. According to this configuration, since the above-described restricting portion (see the folded-back portion 46) restricts the upward movement of the top ceiling 45, the texture thereof can be improved.

Further, the restricting portion is formed by a folded-back portion 46 in which the tip end of the lower end of the bracket 31 is folded back toward the outside of the vehicle. According to this configuration, since the regulation portion is constituted by the folded-back portion 46 folded back to the outside of the vehicle, the top-sealing portion 46 does not interfere with the deployment of the bag member when the curtain airbag 52 operates. Four
5 can be restricted, which is particularly effective when the above-mentioned guide surface 44 is formed on the folded-back portion 46.

Moreover, the bracket 31 is attached to the roof side rail inner 22 at least at two points in the vehicle front-rear direction, one attachment portion 35 is inserted and fixed to the roof side rail inner 22, and the other attachment portion 37 is attached to the attachment member. (See the bolt 38).

According to this structure, one of the brackets 31 has a plug-in fixing structure, and the other has a tightening fixing structure with mounting members such as bolts 38 and nuts. Therefore, the bracket 31 can be manufactured while reducing the number of parts. It is possible to improve the assembling property.
