Description

[Detailed description of the invention] The present invention relates to a passive seat belt device installed in an automobile, and in particular relates to an anchor portion of a pole (also called a tower) provided with one end of the belt protruding above a door panel. This invention relates to improvements to passive seat belts that are installed in vehicles.

When installing a door anchor type passive seat belt on a satsuru door, a door pole 2 is set up above the rear end of the door inner panel 1 as shown in Fig. 1, and one end of the belt 3 is fixed to the upper end of the door pole 2. However, with this structure, the belt 3 does not move forward that much even when the door a is opened, so the belt 3 rubs the chest etc. of the occupant when getting on and off, making it difficult to get on and off the vehicle. There was a problem.

4 is a striker provided on the anchor portion; 5 is a catcher provided on the pillar 6 side of the vehicle body that engages with the striker 4; 7 is a door glass; 8 is a tractor device provided on the floor of the vehicle body; It is a sheet device.

Therefore, as shown in FIG. 2, the rear end of the door inner panel 11 is extended upward to form the door pole 12 integrally.
An idle rail 13 is provided which extends from the upper end of the door pole 12 through the upper part of the door inner panel 11 to near the front end of the door inner panel 11, and a movable anchor 14 moves within the guide rail 13 to secure the door. It has been proposed to move the belt 15 forward when opening a' to solve the above problem. However, with this structure, although the belt 15 can be moved forward, the Since the tip of the belt 15 falls downward, it rubs against the occupant's thighs when getting on and off the vehicle, which again poses the problem of poor ease of getting on and off the vehicle.

16 is a movable anchor drive device, 17 is a door glass, 18 is a tractor device provided on the vehicle body floor 19, and 20 is a seat device.

Therefore, the present invention was devised to solve the above-mentioned conventional problems, and provides a passive seat belt device that moves the belt forward and does not move downward when getting on and off, thereby improving the ease of getting on and off. The purpose is to make things better.

Therefore, in the present invention, the door pole attached to the door panel is rotatable, and when the door is opened, the drive device installed in the door panel rotates the door pole forward, thereby moving the belt anchor forward and upward to achieve the above purpose. This was to prevent them from being distant relatives.

The present invention will be described below with reference to illustrative embodiments.

Reference numeral A denotes a door of a satchelless type installed in an automobile, and is composed of a door panel 21 and a door glass 22.

Reference numeral b denotes a door pole which is rotatably attached to the front door panel 21, and has an oval shape as a whole, with the vertical part serving as the door pole main body 23 and the horizontal part serving as the arm part 24.

The door pole b has its door pole main body 23 at the rear end of the door panel 21.
The tip of the arm portion 24 is rotatably pivotally attached to a substantially central shaft in the upper portion of the door panel 21 by a support shaft 25 so as to protrude further upward.

A substantially fan-shaped gear 26 centered on the support shaft 25 is formed at the tip of the arm portion 24, and the gear 26 is connected to a drive motor 27 operated by a door switch (not shown).
The arm portion 24 is configured to mesh with a worm gear 29 that meshes with the worm 28 of the arm portion 24, and constitutes a drive device that rotates the arm portion 24.

Further, a belt 30 is provided near the upper end of the door pole body 23.
An anchor portion 23a for fixing one end of the vehicle body, and a lock portion 23b that is open downward and in the left-right direction and that engages with a lock pin 32 protruding from a pillar 31 of the vehicle body are formed.

33 is a waist, and 34 is a weather strip.

With the above configuration, when door A is opened, the door switch (
(not shown), the drive motor 27 is operated, and the door pole b can be rotated forward.

Therefore, the end of the anchor portion of the belt 30 also moves forward and upward, making it possible to get on and off the vehicle.

When the door A is closed, the door switch (not shown) is activated again, the drive motor 27 is reversed, and the lock portion 23b of the door pole body 23 engages with the lock pin 32 of the pillar 31, returning the door pole B to its original position. The belt 30 is then returned to the attached state.

Note that a limit switch (not shown) is activated to stop the operation of the drive motor 27 at the open position and the installed position of the door pole b, respectively.

In addition, in the above embodiment, the door pole main body 23 and the arm part 24
Although these are integrally molded, they may be molded separately and connected.

FIG. 5 shows another embodiment of the present invention. In this embodiment, the arm portion 24 is formed in the shape of a semicircle with a support shaft 25 as the center, and its outer peripheral edge is inserted into the door panel 21. It is positioned within a provided guide rail 35 and is configured to slide within the guide rail 35.

According to this embodiment, the outer circumferential edge of the semicircular arm portion slides within the guide rail 35, so that it is possible to prevent the arm portion from wobbling during rotation.

Further, as shown in FIG. 6, the appearance can be improved by extending the rear end of the door trim 36 upward and forming a cover 37 that covers the door pole body 23.

38 is a lock pin through hole bored in the cover 37.

Note that the cover 37 may be formed of a separate member from the door trim 36 and attached.

As described above, according to the present invention, when the door pole that fixes one end of the belt is rotatable, the center of rotation of the door pole is positioned in front of the door from the door pole body that projects upward from the door panel, and the door pole body is moved forward. Since the belt is rotated, when the door is opened, the belt end moves upward in front of the door and does not get in the way of getting on and off, improving the ease of getting on and off. , which is effective when an anchor is provided on the door.

Further, according to the present invention, the center of rotation of the door pole is located at the front, and the door pole is rotated so that the lock portion provided on the door pole body is engaged with the lock pin. The direction in which the lock pin is engaged and disengaged is approximately diagonally above the lock pin, whereas the direction in which the belt is pulled when the belt is attached is approximately diagonally downward. Since the lock is in a free state with respect to the direction in which the door is opened, there is no need for devices such as a lock release device or a delay device (or delay circuit) that allows the door pole to move after the lock is released.
The lock structure can be made simple and lightweight.

Furthermore, when the belt is attached, the opening pin receives the tensile load of the belt, so there is no need to strengthen the door pole.
