DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle equipped with a so-called dual air conditioner having an air conditioner installed in each of a front seat and a rear seat, for example, an air conditioner outlet structure on a rear seat side.

[0002]

2. Description of the Related Art As shown in FIGS. 6 and 7, a duct for a vehicle air conditioner of this type is provided from a cooling unit (not shown) of a dual air conditioner along the inside of a roof side rail portion 101 on the left and right sides of the vehicle. It is configured as a forked ventilation path extending to the side, and an air outlet 102 as an air outlet is provided at several points along the path.
The air outlet 102 is often provided at an upper position near the head of a seated occupant in order to create a better cooling environment for a rear occupant. In many vehicles of this type, an assist grip 103 for an occupant is also mounted at this position. The assist grip 103 is screw-fixed to the roof side rail portion 101 immediately below the air outlet 102 where the occupant can easily reach and reach for gripping, and protrude toward the inside of the vehicle.
Note that both the duct 104 and the roof side rail portion 101 are finally covered with the molded ceiling 105.

[0003]

In the vehicle having the above-described structure, as shown in FIG. 7, a duct 104 is mounted immediately above the assist grip 103, and a duct 104 is provided above the assist grip 103 up to the molded ceiling 105. There is a problem that it is difficult to hold the assist grip 103 when the assist grip 103 is gripped because the distance a between them cannot be large. The problem is that duct 10
4 has a small cross-sectional area, or has been attempted by providing the air outlet 102 and the assist grip 103 apart from each other. However, the solution has been reduced. Another problem is that the optimal position cannot be secured, and the problem remains unsolved.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and its purpose is to reduce the cross-sectional area of a duct for an air conditioner and to determine the appropriate positions of an air outlet and an assist grip. It is an object of the present invention to provide an air conditioner outlet structure for a vehicle in which the assist grip can be easily gripped without being shifted.

[0005]

An air conditioner outlet structure for a vehicle according to the present invention for solving the above-mentioned problems is provided for a dual air conditioner which is piped along the inside of a roof side rail portion of the vehicle and fixed to a roof rein hose. For the air outlet portion opened on the vehicle cabin side of the duct, an air outlet communicating with the air outlet of the duct, and an air outlet formed integrally at a position close to the air outlet along the air outlet direction of the air outlet A cooler register having a protruding assist grip is fixed on the vehicle compartment side.

[0006]

According to the above-mentioned means, the assist grip integrated with the cooler register protrudes from the position close to the air outlet along the blowing direction by fixing the cooler register. The projection amount of the assist grip can be set wider without changing the duct or the positional relationship of the outlet.

[0007]

Next, one embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 3 and 4, the vehicle S of this example is equipped with a so-called dual air conditioner having an air conditioner at the front and rear of the passenger compartment. In FIG. 3, reference numeral 20 denotes a front outlet, which is formed to be able to ventilate through a cooling unit 21 and a blower tube 22 on the front side. Numeral 12 denotes a rear outlet, which is formed so as to be able to ventilate through a rear cooling unit 30, an air duct 31 and a rear duct 1.

FIG. 1 shows the entire vehicle S. FIG. 3 and FIG.
FIG. 3 is an enlarged cross-sectional view taken along line AA of the roof side portion in FIG. 3, in which ducts 1 on the rear side of the dual air conditioner are piped along the inside of the left and right roof side rail portions 2, respectively, where G is Shows window glass. The piping of the rear side duct 1 is assembled as shown in FIGS. 3 and 5.

As shown in FIG. 1, a duct 1 is formed as a resin tube having a substantially trapezoidal cross section by blow molding or the like, and is screwed through a bracket 4 to a roofline hose 3 which is a body structure of the vehicle S. It is fixed at 5. In the duct 1 in the mounted state, the short side is directed to the floor side, the long side is directed to the roof side, and the long oblique side is directed to the vehicle interior side, and the lower surface of the short side is substantially horizontal. On the lower surface of the duct 1, an outlet 6 is formed at an appropriate position. In addition, the right place refers to a position suitable for providing a better cooling environment for a rear-seat occupant, and more specifically, near an upper position near the head of a seated occupant.

[0010] The duct 1, the roof side rail portion 2 and the like are covered by the molded ceiling 7, and are hidden from the inside of the vehicle and are not visible. FIG. 2 shows the air outlet 6 of the duct 1
A cooler register 8 is mounted and fixed from the inside of the vehicle by two screws 9 and a fixing hook 10 as shown in FIG. The cooler register 8 includes a grid-shaped outlet 12 communicating with the outlet 6 of the duct 1 on a base 11 having a rectangular base,
This is a resin molded product having an assist grip 13 formed in the front-rear direction of the vehicle by integral molding at a position close to the outside of the outlet 12 and protruding along the blowing direction of the outlet 12.

The projecting amount of the assist grip 13 is set to be larger than a normal one on the basis of the ease of grasping, and a screw insertion hole 14 for fixing is formed at the base thereof.
The fixing hooks 10 are integrally formed one by one in the front-rear direction of the vehicle on the mounting surface side of the base 11 facing the assist grip 13 near the side. The fixing hook 10 can be hooked on the edge of the outlet 6 of the duct 1 and is used together with the two screws 9 to fix the cooler register 8 to the outlet of the duct 1.

In the air-conditioner outlet structure having the above structure, the assist grip 13 integrated with the cooler register 8 protrudes toward the inside of the vehicle along the blowing direction from a position close to the outside of the outlet 12 by fixing the cooler register 8. That is, between the assist grip 13 and the molded ceiling 7, the duct 1 is made thinner, the sectional area is changed, or the air outlet 1 is formed.
Assist grip 1 without changing the positional relationship with 2
By setting the amount of protrusion of 3, the width can be made sufficiently large, and the assist grip 13 can be used without feeling narrow.
The function of the air outlet 12 is not hindered at all by an increase in the protrusion amount of the assist grip 13, and the number of parts and the number of assembling steps are reduced as compared with the above-described conventional example, so that the cost is also reduced. Of course, the position of the air outlet 12 and the position of the assist grip 13 are each in a proper position, and do not impair the functions.

Although the air conditioner outlet structure of this embodiment is applied to the air outlet of the rear duct of the dual air conditioner, it can be provided on the front duct, for example, on the ceiling on the passenger side window side.

[0014]

As is apparent from the above description of the embodiment, according to the present invention, by fixing the cooler register, the assist grip integrated with the cooler register projects from the position close to the outlet in the blowing direction. become,
The gap between the assist grip and the molded ceiling can be made sufficiently wide by setting the amount of protrusion, so that the cross-sectional area of the duct can be reduced, and the appropriate position of the outlet and the assist grip can be shifted. The grip of the assist grip can be easily obtained.
