Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a safety pad insert that doubles as a duct for connecting an air conditioning heater and a heater register in an automobile instrument panel.

Prior Art In the conventional instrument panel A shown in FIG. 3, the connection structure between the safety pad B and the register C and the heater side located on the vehicle front side of the instrument panel is as shown in the cross-sectional view of FIG. 4. A resistor C is inserted into a pad insert D covered by B, one end of a duct E connecting the resistor C and the heater F is screwed to the opening G of the heater F, and the other end is connected to the end of the resistor C. The protruding portion at the other end is screwed to the boss H of the pad insert D, so that the duct E is supported by the pad insert D, and both the resistor C and the heater F are connected to the pad insert D. Those connected by duct E, or those connected by duct E, or
As shown in Publication No. 57113, a duct is provided with a distribution plate corresponding to a partition panel at the end of the air outlet that is formed integrally with the instrument panel, and the duct is formed into two compartments, There is a known structure in which the compartments are opposed, butted and connected by a locking means such as a locking piece to form a duct, and the duct connects the air outlet and the air supply port of the heater main body. It was getting worse.

Problems to be Solved by the Present Invention The devices shown in FIGS. 3 and 4 described above merely provide a separate duct between the heater and the resistor to connect them. It has the disadvantage that assembly man-hours cannot be reduced, and
In the duct shown in Publication No. 57113, the duct connecting the instrument panel and the heater is formed with two compartments in order to improve the wind direction, and a distribution plate is provided inside the duct, resulting in a complicated shape. The disadvantage was that the number of man-hours for processing and assembly increased. Therefore, a separate duct is not used, the duct structure is simple, ventilation passages are secured,
There was also a need for something that would reduce the number of parts and assembly man-hours.

In view of the current state of the conventional structure described above, the present invention does not make the duct connecting the heater and the register a separate part, but instead extends the pad insert in a cylindrical shape toward the heater and fits into the heater opening. This was devised for the purpose of providing a pad insert for an automobile safety pad that has a structure that allows for ventilation passages, and reduces the number of component parts, processing, and assembly man-hours. It is.

Means for Solving the Problems As described in the claims of the utility model registration, the present invention provides a pad insert of a safety pad in an automobile instrument panel, which includes a first cylindrical portion for fitting a resistor, and a pad insert of a safety pad in an automobile instrument panel. A second cylindrical portion extending from the cylindrical portion to the heater side located on the vehicle front side of the instrument panel is integrally formed, and the end of the second cylindrical portion is fitted into the heater side opening. With this structure, the ventilation duct part that connects the heater and the register is integrated with the pad insert, and the shape is such that a ventilation passage can be secured, and there is no need for a separate duct.
By reducing the number of components, it is possible to reduce the number of parts processing and assembly processes, improving economic efficiency, and the stepped cylindrical shape that is the extended mating part of the pad insert. The structure increases strength due to its shape and increases the space for ventilation passages.

Embodiment and operation FIGS. 1 and 2 show an embodiment of the present invention, and FIG. 2 shows an automobile instrument panel 1.
This is a perspective view taken from the passenger compartment side, the surface of which is covered with the safety pad 2, and the opening 4 located below is shown in the register 5 shown in FIG.
is inserted so as to be connected to the heater side located on the front side of the vehicle of the instrument panel 1, and is fixed by a bolt etc. screwed into the mounting hole 13,
The end face of the ventilation port of the register 5 is arranged flush with the safety pad 2.

FIG. 1 is a sectional view showing the outline of the structure of the instrument panel 1. Inside the pad insert 3 of the safety pad 2, a stepped first cylindrical portion 6 connected to the register 5 faces toward the heater 8. It extends in the longitudinal direction so as to hold the fitting part 11 which is the end of the register 5, and the inner diameter of the cylinder part 6 is the same as that of the register 5.
The heater 8 is dimensioned to closely fit the outer diameter of the fitting portion 11 through the sealing material 7, and the heater 8 is
A second cylindrical portion 9 extends toward the register 5 , and the outer diameter of the cylindrical portion 9 is dimensioned to fit into the inner diameter of the heater-side opening 10 of the heater 8 . The length of the cylindrical portion 9 is such that the end portion 14 of the cylindrical portion 9 is held in the opening 10. Further, the inner diameter of the ventilation passage 12 adjacent to the fitting portion of the opening 10 on the heater 8 side is approximately the same as the inner diameter of the cylindrical portion 9. A ventilation passage is formed by the register 5,
The passage has a smooth shape with no uneven parts.

Operation The operation of the embodiment described above will be explained with reference to FIGS. 1 and 2. As shown in FIG. 1, the end 14 of the extended second cylindrical portion 9 of the pad insert 3;
into the heater 8 side opening 10, then insert the resistor 5 from the opening 4 of the pad insert 3 toward the heater 8 side, and insert the resistor 5 into the fitting part of the first cylindrical part 6. Then, the fitting part 11 is easily fitted, and by further tightening the resistor 5 with the bolt screwed into the mounting hole 13 shown in FIG. Both the fitting part 11 and the fitting part 11 are held airtight by the sealing material 7, and as shown by the arrow in FIG. 2nd insert of insert 3
The air is blown into the vehicle interior from the register 5 through the cylindrical part 9 and the first cylindrical part 6, which is the connection part with the register 5. Furthermore, as described above, the inner diameter of each of the sections serving as the ventilation passage is a smooth and simple shape with no steps, so that it functions as a ventilation passage with less air resistance than the conventional one.

Effects of the present invention The present invention has the structure described above, and unlike the conventional structure in which a separate duct is provided for the ventilation passage from the heater to the register and assembled with screws, etc., the present invention uses a pad insert. A second cylindrical part is provided such that the end thereof is fitted into the heater opening, and a second cylindrical part is provided such that the resistor is fitted into the extending part of the pad insert. 1 cylinder part, the duct between the heater and the register is formed integrally with the pad insert, and the structure has a simple shape with no joints using bolts etc., so that a ventilation passage can be secured. According to this structure, it is possible to reduce the number of parts and assembly man-hours, which has the effect of reducing processing costs.In addition, the shape of the ventilation passage is simple, and it is possible to reduce the number of parts and the number of assembly steps. Since the inner diameter can be maintained, it is possible to obtain a duct with low ventilation resistance, and by forming the above-mentioned first and second cylindrical parts in the pad insert, the strength of the pad insert can be increased. It is something that makes you play.
