Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side defroster device for a vehicle, in which wind blown from a blower source is jetted and supplied to the inner surface of a door window to perform an anti-fog function.

[0002]

[Prior Art]

 As a conventional vehicle side defroster device, the opening end of the defroster duct faces the opening provided in the instrument panel, and a cushion that abuts the opening surface of the side duct provided on the door side is provided at the opening end of the defroster duct. The wind (warm air) sent from the defroster duct is provided on the door by holding and inserting and holding the flange at the base end of the cushion overlapping and holding it on the inner surface of the peripheral edge of the opening of the instrument panel. Some are designed to be sent to a side duct (see Japanese Patent Publication No. 61-52009).

However, in the case where the cushion flange is superposed and held on the inner surface of the peripheral edge of the opening provided in the instrument panel as described above, when the reaction force due to the contact with the door is repeatedly generated in the cushion, Due to this reaction force, the flange may be peeled off from the inner surface of the instrument panel, and the sealability between the side duct and the side duct may deteriorate.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such a situation, and an object thereof is to provide a vehicle side defroster device which is excellent in reliability and durability in which sealing performance does not deteriorate with opening and closing of a door. There is.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a side duct which is provided with a cushion at an opening end of a defroster duct guided from an air source to an end of an instrument panel, and a side duct which faces the opening end of the defroster duct. In a vehicle side defroster device in which the defroster duct is connected to the side duct via the cushion so that the defroster duct can be connected to and separated from the side duct, it is fitted into the opening provided in the instrument panel from the front side of the panel. A case is provided that is fixed and forms the open end of the defroster duct. In addition, a flange that overlaps the peripheral surface of the opening provided in the instrument panel is provided on the inner peripheral surface of the base end of the cushion, and a flange that presses and fixes the flange to the surface of the instrument panel is provided in the case. It is characterized by that.

[0006]

[Action]

 Since the flange provided on the inner peripheral surface of the base end of the cushion is pressed and fixed to the surface of the instrument panel using the flange of the case, the cushion flange is sandwiched between the instrument panel and the case flange. Fixed. Therefore, the force acting in the direction of pushing the cushion is supported by the instrument panel, and the force acting in the direction of peeling the cushion is supported by the flange of the case, so that the door is repeatedly opened and closed. Even if pushing force or peeling force is applied to the cushion, the cushion does not come off, and deterioration of the sealing property between the defroster duct and the side duct is prevented.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a sectional view showing an embodiment of a vehicle side deflector device according to the present invention, FIG. 2 is a perspective view of the cushion shown in FIG. 1, and FIG. 3 is a front view of the case shown in FIG. 4 is a rear view of FIG. 3, FIG. 5 is a plan view of FIG. 3, FIG. 6 is a sectional view taken along line AA of FIG. 4, FIG. 7 is a sectional view taken along line BB of FIG. 4, and FIG. FIG. 9 is a sectional view taken along line C-C and FIG. 9 is a sectional view taken along line D-D in FIG. 4.

In these figures, a defroster duct 2 is guided from an unillustrated heater unit to an end of an instrument panel 1 of a vehicle, and an open end of the duct 2 is exposed to an opening 3 provided in the instrument panel 1. No The door 4 is provided with a side duct 5 that faces the opening 3 and an outlet 6 that is opened toward the inner surface of a glass (not shown) is provided in the side duct 5, so that the defroster duct 2 The hot air supplied to the side duct 5 through the cushion 7 is jetted from the outlet 6 to the inner surface of the glass to prevent the glass from being fogged.

A flange 8 is provided on the inner peripheral surface of the base end of the cushion 7, and a flange 10 of a case 9 fitted and fixed in the opening 3 from the surface of the instrument panel 1 is used. 8 is pressed and fixed to the peripheral surface of the opening 3 in the instrument panel 1. Then, by inserting and engaging the inner end of the case 9 with the opening end of the defroster duct 2, the cushion 7 is attached to the peripheral surface of the opening of the side duct 5 with the door 4 closed as shown in FIG. The defroster duct 2 is connected to the side duct 5 in an airtight manner by maintaining pressure contact.

The flange 8 of the cushion 7 is provided with a plurality of engaging holes 11 as shown in FIG. By providing it on the back surface of the flange 10, slippage does not occur between the flanges 8 and 10 when the cushion 7 is pressed and fixed by the case 9. Reference numeral 13 is an engaging claw that elastically engages the inner surface of the peripheral edge of the opening 3 of the instrument panel 1 to fit the case 9 into the instrument panel 1 to hold it, 14 is a claw for preventing the defroster duct 2 from coming off, and 15 The ribs serve to prevent deformation of the case 9, and the cushion 7 is made of rubber, for example, and the case 9 is integrally formed of a hard resin material.

In the vehicle side defroster device configured as described above, the wind guided to the end of the instrument panel 1 by the defroster duct 2 is introduced into the side duct 5 through the case 9 and the cushion 7. .. Then, it is jetted and supplied from the blow-out port 5 provided in the side duct 5 toward the inner surface of the glass covering the window (not shown) to perform the defrosting action of the glass.

Further, when the door 4 is closed, the cushion 7 is pushed toward the instrument panel 1 side as shown in FIG. 1, but when the door 4 is opened, the pushing force by the door is lost, or A tensile force may be applied to the cushion 7 by a twisting force or a tensile force generated between the cushion 7 and the door 4. However, since the flange 8 provided at the base end of the cushion 7 is sandwiched and fixed between the instrument panel 1 and the flange 10 of the case 9, an external force is applied to the cushion 7 when the door 4 is opened or closed. The cushion 7 is stably held by the instrument panel 1 even when the cushion 7 is released.

Therefore, at least when the door 4 is closed, the wind blown into the defroster duct 2 is surely sent into the side duct 5, and a good defrosting action is performed. Further, since the cushion 7 can be securely attached by fitting and engaging the case 9 into the opening 3 of the instrument panel 1 without using an adhesive or the like, the workability of attaching the cushion 7 is high. Become.

In the embodiment, the flange 8 of the cushion 7 is provided with the engaging hole 11, and the claw 12 which is inserted into the engaging hole 11 is provided on the flange 10 of the case 9 to provide the flange 8 of the cushion 7. However, the contact surface of the flanges 8 and 10 may be roughened instead of the engagement hole 11 and the claw 12 to increase the sliding frictional force therebetween.

[0015]

[Effect of the device]

 As is apparent from the above description, according to the present invention, the flange of the cushion is pressed and fixed to the surface of the instrument panel by using the case fitted and fixed to the opening of the instrument panel from the surface side. Therefore, the workability of installing the cushion is improved, the stability of installing the cushion against external force is improved, and the leakage of the air due to the defective installation of the cushion or the fall of the cushion is prevented, so that the durability and reliability of the side defroster device are improved. Becomes higher.
