Description

[Detailed Description of the Invention] This invention relates to a seatbelt device, and particularly to a seatbelt device in which one end of the seatbelt is attached to a door pole provided on a seatless door.

An example of a conventional seatbelt device in which one end of a seatbelt is attached to a door pole provided on a seatless door is shown in FIG.

In the figure, 1 is a door for an automobile, 2 is a door glass, 3 is a door pole located on the inside rear of the window shoulder of the door 1 and protrudes upward, and 4 is a door pole attached to the top of the door pole 3 via an anchor 5. It is a seat belt with one end attached.

In the above, the other end of the seat belt 4 is attached to the vehicle body via a retractor at the lower side of the seat on the center side of the vehicle, straddling the seat (not shown).

Therefore, when a passenger opens the door, takes a seat, and closes the door, the seat belt is automatically fastened, resulting in a so-called passive seat belt system. (Refer to Japanese Unexamined Patent Publication No. 55-22576.) However, in the case of such a conventional passive seat belt vehicle's bushless door, when the door glass 2 is lowered from the upper end of the door pole 3, the door pole 3 is lower than the door 1. Since the vehicle protrudes upward, there is a problem in that the upper end of the door pole 3 at the shoulder of the door window catches or hits the person getting on or off the vehicle when getting on or off the vehicle.

This idea was created by focusing on these conventional problems.If the door is opened while the door glass is still lowered, the door glass is automatically raised, and the door glass is placed on the door pole. The purpose is to solve the above problem by locating it above the upper end.

This invention will be explained below based on the drawings.

FIG. 2 is a diagram showing an embodiment of this invention. Note that the same members as those shown in FIG. 1 are given the same reference numerals and redundant explanation will be omitted.

First, to explain the configuration, 6 is a limit switch, and this limit switch 6 is within the range where the door glass 2 does not reach the set height position (door pole 3
In the lower position), the door glass 2 is turned on, and the door glass 2 rises along the glass guides 7, 7a.
They are arranged so that they are turned off when they reach a set height position (a position elevated above the door pole 3).

The limit switch 6 is further connected in series with a door switch 8, and a motor 9 (power source) (not shown in FIG. 2) that raises or lowers the door glass 2 rotates when both switches 6 and 8 are respectively on. Connected as possible.

On the other hand, the door switch 8 is disposed oppositely between the door 1 and the body 10 so as to be turned on when the door 1 is opened.
It may be either the 0a portion or the front pillar 10b portion (for example, 8' in the figure).

Note that the door switch 8 is located at the 8' position shown in the figure.
That is, when it is provided on the front pillar 10b side, it is possible to adjust the opening/closing angle of the door, so that the raising of the door glass 2 cannot be restricted unless the door 1 is opened to the extent necessary for getting on and off the vehicle. This also helps to eliminate the inconvenience of the door glass 2 rising in the direction of closing the window each time when the door glass 2 is lowered and the door 1 is slightly opened or closed, not for boarding or exiting. .

Reference numeral 11 denotes a switch for raising and lowering the door glass 2. As shown in Fig. 3, this switch 11 has a switching configuration of 2 circuits and 3 circuits, and is normally connected in the state shown in the figure (contact a is connected to terminal a ₁₎ . , the contact piece b is connected to the terminal _b1 ), and is urged by a spring or the like so that it can return. Therefore, in this case, if limit switch 6 and door switch 8 are both turned on,
The motor 9 automatically rotates in a direction to raise the door glass 2.

In addition, when raising and lowering the door glass 2 by manual operation, by switching the selection position of the contacts a and b of the switch 11 to the terminals a ₂ and b ₂ side, the polarity of the DC power supply to the motor 9 is reversed. The motor 9 rotates in the direction of lowering the door glass.
Although the above-mentioned reversal of the motor 9 is omitted in the illustration, a limit switch is actually provided to detect the lowest position of the door glass 2, so that the door glass 2 can be lowered without any trouble. It is configured so that

If the switch 11 is further manually operated to switch the selection circuit to the terminals a ₃ and b ₃ , DC power can be directly supplied to the motor 9 with the normal polarity, and the door glass 2 can be raised freely. In the above,
When the manual operation of the switch 11 is stopped, the switch operation section returns to the state of the automatic circuit.

Next, the effect will be explained.

The door glass 2 can be raised and lowered by a motor 9 installed inside the door 1, and the door glass 2 is turned on when the limit switch 6 is turned on when the door glass 2 is lowered from a set height position and the door 1 is opened. When both the door switch 8 and the door switch 8 are turned on, the motor 9 rotates, and the door glass 2, which has been lowered every time the door 1 is opened, can automatically rise to the upper position of the door pole 3. Then, the above-mentioned increase is stopped when the limit switch 6 is turned off.

As explained above, according to this idea,
In a vehicle equipped with a passive seatbelt device, in which a door pole is provided behind the window shoulder of the sliding door and one end of the seatbelt is attached to the door pole, if the door is opened with the door glass lowered below the upper end of the door pole, Because the door glass is configured to automatically rise above the top of the door pole, it is common for people to accidentally get clothes, etc. caught on the tip of the door pole, or bump into it when opening a door with a door pole and getting in or out. This has the effect that dangers such as these can be prevented before they occur.
