Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a window lifting device for a vehicle, and is particularly applicable to a window glass whose front lower end is tilted forward at a predetermined angle of inclination and extended downward. This invention relates to improvements to the X-link type.

(Prior Art) Conventionally, a vehicle window elevating device includes a carrier plate in a side door panel that extends from the rear to the front of the window glass to hold the lower end of the window glass. A main arm connected to the window lifting/lowering drive means and having an upper end slidably connected to the rear of the carrier plate, a main arm swingably connected to the center of the main arm, a lower end connected to the side door panel, and an upper end connected to the carrier plate. The sub-arms are each slidably connected to the front part of the plate.
An X-link type, which is equipped with X-links arranged in a letter shape, and the window glass is moved up and down by link movement of the X-links (main arm and sub-arm) by the window driving means. is well known and widely used in actual vehicles.

By the way, in vehicles such as cab-over type cars where the driver's seat is installed at a high position, a sloped part that tilts forward at a predetermined angle of inclination is provided at the lower front end of the side door panel, and the door panel is connected to the door panel through this sloped part. It is necessary to provide a gouge to ensure visibility to the front and sides. Therefore, when the X-link type window lifting device is installed on the door of this type of vehicle, it is moved rearward to avoid interference with the inclined portion.

(Problem to be solved by the invention) However, in this case, the front lower end of the window glass is extended downward to correspond to the above-mentioned inclined part, so the center of gravity of the glass moves forward. As described above, as the window lifting device moves rearward, the connection point between the carrier plate and the sub-arm moves rearward, and the amount of offset between this connection point and the center of gravity of the glass decreases. As a result, the windshield tends to tilt forward,
When the window glass is fully closed, there is a problem in that the sealing performance at the front upper end of the window glass deteriorates.

Therefore, in order to solve this problem, for example, as disclosed in Japanese Utility Model Application Publication No. 124482/1982, the main arm of the above-mentioned The main arm is divided into two parts between the fulcrum and the main arm, which bends inward to correct the horizontal position of the windshield when the window glass is raised. A number of proposals have been made to improve this.

However, with the above proposal, there is a risk that the main arm may bend undesirably due to vehicle body vibrations and resistance of the sliding surface of the windshield, and the windshield may swing back and forth when the windshield is raised or lowered. There is a concern that it will not be possible to move up and down smoothly.

The present invention was developed in view of these points, and its purpose is to improve the carrier plate so that the connection point between the carrier plate and the sub-arm can be placed forward, and to offset the connection point between the connection point and the center of gravity of the glass. The objective is to secure the amount so that the window glass can be raised and lowered in a stable horizontal state at all times, and to improve the sealing performance at the upper end of the window glass.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention is such that the upper opening of the side door panel is tilted forward at a predetermined angle of inclination from the front lower end of the upper opening. The lower end of the front of the window glass extends downward corresponding to the inclined part, and the lower end of the window glass extends from the rear to the front of the window so as to hold the lower end of the window glass within the door panel. An X-link formed by arranging a main arm and a sub-arm in an X-shape is connected to the extending carrier plate, and the link movement of the X-link moves the carrier plate up and down to move the window glass up and down. This assumes a vehicle window lifting device. and elongated holes are provided in the front and rear parts of the carrier plate to slidably support the connecting point of the main arm and the connecting point of the sub-arm to the carrier plate so as to enable link movement by the X-link, The carrier plate has a stepped shape in which the front part of the carrier plate is extended toward the inclined part so that the front part of the carrier plate is located below the rear part of the carrier plate, and the long hole in the front part is made closer to the long hole in the rear part. The structure is such that it is also positioned below.

(Function) With the above configuration, in the present invention, the carrier plate has a stepped shape in which the front part is extended toward the inclined part so that the front part is located below the rear part, and the front part of the carrier plate is long. The hole (that is, the connection point of one of the main arm or the sub-arm to the carrier plate) is located below the elongated hole at the rear of the carrier plate (that is, the connection point of the other sub-arm or main arm to the carrier plate). As a result, the connection point of one of the main arms or sub-arms has a panel length that gradually increases forward as it goes downward at the inclined part of the side door panel, compared to the conventional case where the carrier plate is straight. By effectively utilizing the main arm or sub-arm, it can be installed forward while avoiding interference with the sloping part, and as a result, there is a sufficient offset between the connection point of one of the main arms or sub-arms to the carrier plate and the center of gravity of the window glass. This means that the window glass can be stably raised and lowered in a horizontal state.
