Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conshield type rear wiper (hereinafter, simply referred to as rear wiper). More specifically, it is a rear wiper that is structured to store the wiper arm so that it cannot be seen from the outside when not in use. It includes both.

[0002]

2. Description of the Related Art Recently, an increasing number of vehicles are equipped with rear wipers. This is because the rear window of a running vehicle is directly hit by rain and snow, and dirt on the road surface is rolled up by the airflow at the rear of the vehicle, which reduces rear visibility.

Conventionally, a rear wiper has a hole 50 formed in a rear window W as shown in FIG. 4, and a holder portion of a drive portion 52 is inserted into the hole 50 and fixed with a nut 51.
The drive unit 52 and the wiper arm 53 are connected by tightening with a nut. As shown in FIG. 5, the upper part of the drive part 52 projects above the package tray (also referred to as the rear parcel shelf) 54 at the rear of the rear seat, and the motor main body 55 is arranged below the package tray 54. Therefore, the drive unit 52 is covered and protected by the cover 56 and the cover 57.

[0004]

However, in the rear wiper shown in FIGS. 4 and 5, the wiper arm 53 is always exposed to the outside of the rear window W, which is not preferable from the viewpoint of appearance design.

Further, since a hole is provided in the glass of the rear window W to attach the glass, a dedicated glass having a hole is required, and a part of the driving portion 52 penetrates into the vehicle compartment, so that the package tray 54 is also standard. There is a problem that a special notch different from the above is required, which leads to an increase in the kinds of parts and cannot reduce the cost.

Further, at the time of mounting work, it is necessary to mount the drive unit from the inside of the vehicle compartment and fix the wiper arm from the rear side of the vehicle body outside the vehicle, which requires two people, and sometimes two people. There is also a problem that it takes time and effort.

Further, there is a demand for providing a high mount stop lamp at the relevant portion of the rear window W to improve safety, but the drive portion 52 is provided above the package tray 54.
There is a problem that a cover 56 for covering the above is protrudingly provided, and it is structurally difficult to provide the high mount stop lamp at the same place.

In view of the above circumstances, the present invention has an excellent external appearance design, can reduce the number of kinds of parts to reduce the cost, and the mounting work can be done easily.
It is an object of the present invention to provide a concealed rear wiper which can be equipped with other members such as a high mount stop lamp.

[0009]

The rear wiper of the present invention comprises:
A wiper arm that detachably supports the wiper blade,
A rain shaft formed of an arm shaft fixed to the base part of the wiper arm, a shaft part that rotatably supports the arm shaft, and a drive part that swings the arm shaft, and extends below the rear window. A hole is bored in the channel to fix the shaft portion, and the wiper arm is housed so as to be hidden by the front edge portion of the trunk lid.

It is preferable that the arm shaft and the drive unit are connected by a cable or a rod. Further, the arm shaft and the drive unit may be directly connected.

[0011]

In the rear wiper of the present invention, the hole is attached not to the glass (rear window) at the rear of the vehicle but to the rain channel below the rear window. The position of the hole is below the front edge of the trunk lid, and the wiper arm and the wiper blade can be hidden by the front edge of the trunk lid. Also, it does not require a dedicated glass with holes,
Installation work can be performed from the rear side of the vehicle body.

Further, by connecting the arm shaft and the drive unit with a cable or a rod, the drive unit can be installed at any position without hindering the trunk space. When a compact motor drive unit that does not obstruct the trunk space is used, by directly connecting the arm shaft to the drive unit, the cable rod becomes unnecessary, and the rear wiper system becomes highly efficient and inexpensive.
