Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a side defroster structure of a door provided with an outlet from a duct formed between an inner panel of a door and a door trim toward a door glass.

[Prior Art] Conventionally, a structure shown in FIGS. 10 and 11 has been known as a door side defroster structure.

As shown in FIG. 10, in the door side defroster structure 70, a defroster opening 77 is formed in the upper surface 76A of the shoulder garnish 76 of the door garnish 72. Also, on the back side 76B of the Sjorder garnish 76,
A duct forming member 78 is joined, and hot air or cold air 80 blown from the instrument panel side is passed through a duct formed by the duct forming member 78 and the shoulder garnish 76 to the door glass through the opening 77. It is designed to spray.

However, when this door side defroster structure 70 is applied to a vehicle having a door frame, when the door frame garnish 74 and the shoulder garnish 76 are integrally molded by injection molding, the upper surface of the shoulder garnish 76 is The opening 77 for the defroster provided in 76A is the first
As shown in FIG. 1, the angle is a negative angle with respect to the die-cutting direction (the direction of arrow K in FIG. 11). Further, it is difficult to form both the door frame garnish 74 and the opening 77 by negative angle processing of a slide core or the like.

For this reason, it is difficult to integrally mold the door frame garnish 74 and the garnish shoulder 76 of the garnish 72.

Therefore, since the garnish 72 is composed of two parts, the garnish 74 for the door frame and the shoulder garnish 76, the parting lines 81 and 82 are formed at the joint of these two parts, and the appearance quality of the garnish 72 is deteriorated. There was a problem.

[Problem to be Solved by the Invention] The present invention has been made in view of the above facts, and has as its object to obtain a door side defroster structure that can improve the appearance quality of a garnish.

[Means for Solving the Problems] In the door side defroster structure of the present invention described in the utility model registration claim (1), the garnish door frame portion forming the vehicle compartment side portion of the door frame portion is provided. A garnish shoulder portion integrally formed with the garnish door frame portion and constituting a cabin side portion of the door shoulder portion; and a defroster duct joined to the vehicle outside portion of the garnish shoulder portion. A duct forming member to be configured; a notch portion formed at each joint portion of the duct forming member and the garnish shoulder portion to form a defroster outlet at both sides; and a notch portion formed at each of the notch portions for the defroster. And an engaging portion for locking the outlet grille.

[Action] According to the door side defroster structure of the present invention described in the utility model registration claim (1), the garnish door frame portion and the garnish shoulder portion are integrally formed and the duct is formed. Notches forming a defroster outlet are formed at both joints between the forming member and the garnish shoulder portion.

Accordingly, since the defroster air outlet of the garnish is composed of the cutout of the duct forming member and the cutout of the garnish shoulder, the garnish is formed integrally with the engaging portion. The door frame and the garnish shoulder can be integrally formed by injection molding. As a result, the parting line between the garnish door frame and the garnish shoulder is not exposed to the passenger compartment.

Further, the engaging portion formed in the cutout portion of the garnish shoulder portion can be easily formed simultaneously when the garnish door frame portion and the garnish shoulder portion are integrally formed. On the other hand, the engaging portion formed in the cutout portion of the duct forming member can be easily formed simultaneously with forming the duct forming member. Therefore, by coupling the garnish and the duct forming member after molding, it is possible to form an engaging portion for locking the defroster outlet grille all around the defroster outlet.

That is, according to the door side defroster structure of the present invention described in the utility model registration claim (1), the garnish door frame and the garnish shoulder can be integrally injection-molded. In addition to eliminating the parting line between the garnish door frame portion and the garnish shoulder portion, an engaging portion for locking the defroster outlet grille is provided all around the defroster outlet. Since the engagement portion is formed at a predetermined position, the grill for the defroster outlet and the garnish can be flushed.
