[Conventional technology]

A three-point seatbelt system using continuous webbing is used as a seatbelt device for vehicles. There is a device that is used as a root device. In this three-point seat belt device, for example, one end of the webbing is attached to the retractor. For example, the other end is fixed to It passes through an anchor and is secured to an anchor plate located at the bottom of the vehicle. This ue When the webbing is not attached, one end of the webbing is taken up by the take-up device. , the vicinity of the other end shall be placed along the vehicle body behind the side of the passenger seated on the seat. become.

0003 When installing this webbing, the crew must attach the anchor plate and through anchor. Pull out the middle part of the webbing from the take-up device, and attach the tongue plate to the buckle. engage. In this way, the webbing is stored behind the passenger's side when the webbing is not attached. Depending on the vehicle type or the seating position of the occupant, the seated occupant may The distance between the webbing you are trying to grasp may become longer in the longitudinal direction of the vehicle. . In this case, when the occupant attaches the webbing, the occupant's upper body must be twisted significantly toward the rear of the vehicle. Intermediate part of webbing or tongue play between anchor plate and through anchor the webbing must be pulled out of the retractor by grasping the handle.

0004 The above-mentioned three-point seat belt device connects the webbing to the center pillar as described above. The tongue plate is supported near the top and bottom of the seat, and the tongue plate installed between A buckle attached to a vehicle body part (floor or a member fixed to the floor, etc.) in the lower part of the armpit. Shoulder belt and lap belt become one continuous belt when engaged. form a grid. Such three-point seat belt devices generally have an anchor at the lower end of the seat belt. Alternatively, it is attached to the lower part of the center pillar via a mounting member such as a retractor, and the The attachment member is tilted so that it almost matches the direction in which the lower part of the belt that will become the lap belt is pulled out. Because the shape protrudes forward, especially in the case of two-door cars, the rear This poses a major obstacle for passengers to get on and off the seats.

[0005] Therefore, in a three-point seatbelt system, the lower attachment member of the seatbelt is attached to the rear. There are various proposals aimed at solving the conventional problems that hinder getting in and out of seats. Many things are being done. These proposals include, for example, Utility Model Application No. 52-121020; No. 6-130752, No. 60-75156, JP-A-56-34545, etc. There is. Among the above-mentioned publications, in JP-A-56-34545, as shown in FIG. , the seat 10 and the outer boot 4 covering the anchor are connected by a rod 80. ing. This connection structure provides an anchor when the seat 10 is slid forward. - and outer boots 4 are interlocked, and this outer boot 4 is attached to the center pillar 40. Stand upright along the line. This causes obstruction to the webbing 6 when getting in and out of the rear seat. is avoided. Moreover, in Utility Model Application Publication No. 60-75156, as shown in FIG. - The boot 4 is connected to the seat back 12 of the seat 10 by a wire 81. This allows the anchor boot 4 to stand up when the seat back 12 is tilted. It works just like that. This allows the webbing 6 to be adjusted when getting on and off the rear seat. Failures are prevented.

[0006]

[Problem that the idea aims to solve]

In this way, conventional outer boots are useful for getting in and out of the back seat, as mentioned above. For this purpose, a structure has been proposed that operates so that the webbing does not become an obstacle. death However, in the structure shown in Figure 7, when the seat is moved forward, the tip of the boot separates from the seat. It operates as if it were The operation of pulling the webbing for this purpose is to move the seat forward. The further you move it, the harder it becomes. In other words, if the occupants are small, they will be able to pull together to some extent. It becomes difficult to operate. Also, the movement of the tip of the boot is in the opposite direction to the movement of the seat. This may cause it to be difficult to get the webbing in the correct position, causing it to sag. The fit of the webbing was poor.

[0007] In addition, with conventional outer boots, the boot is designed to avoid obstacles when getting in and out of the rear seat. In order to store the outer boot on the center pillar side, the spring and rear Some utilized the winding force of the tractor. In this case, increase the spring torque. If it is too high, the outer boots will tend to stand up more than necessary when worn, resulting in the webbing. If the spring is slack or the spring force is weakened, the spring may become loose when getting into or out of the rear seat. If the outer boots do not return to the specified position naturally, the webbing may become an obstacle. There was a problem. For this reason, the forward tilt angle of the outer boots when the webbing is attached is to prevent sagging. Setting the appropriate angle is an extremely important element in terms of prevention. i.e. , if the occupant did not wear the webbing in such a way as to take up the slack, this slack Problems such as the seatbelt becoming ineffective in restraining the occupant due to was there. In this way, the problem of this invention is to ensure that the outer boots are suitable regardless of the seat position. A comfortable position can be secured, and there is no obstruction when getting in and out of the rear seats. An object of the present invention is to provide a seatbelt device that can operate in the same manner as described above.

[0008]

[Means to solve the problem]

The above problem related to the present invention is that the webbing is supported at the upper part and the lower part of the car body. , the supporting part of the lower part of the vehicle body is covered with an outer boot, and the webbing is Engage the inserted tongue plate with the buckle attached to the vehicle body member in the center of the vehicle. In the three-point seat belt device, the outer boot is attached to the vehicle body. The outer boot is held swingably in the front and back direction, and the outer boot is attached to an elastic member in a certain direction. one end of a first wire rod that is biased and has flexibility on the opposite side of the elastic member; is attached, and the other end of the wire is fixed to the seat part of the seat, and the seat The tip of the outer boot moves in the same direction as the outer boot moves back and forth, and the first The connecting member inserted through the wire rod and the seat back are connected by a second wire rod. , the first wire rod is moved in conjunction with the forward tilting or rising motion of the seat back. A seat belt device configured to be pulled by the second wire rod. This can be solved by placing

[0009]

[Effect]

The outer boot is connected to the seat seat part by the first wire rod and is used to move the seat. The tip of the outer boot moves in the same direction as the movement direction (forward tilting or standing upright movement). By doing this, when you put on the webbing, the tip will always be close to the rear side of the seat. This makes it easier to pull out the webbing. In addition, The webbing can be held in a position where it is easy to put on, so it is easy to use when putting on the webbing. This ensures that no sagging or twisting occurs. Further, one end of the second wire is slidably connected to an intermediate position of the first wire. At the same time, the other end is fixed to the seat back and rotates as the seat back rotates. This allows the second wire to pull the first wire. Therefore, this pull The outer boot can be operated in an upright position by the folding motion, making it possible to operate the outer boot in an upright position. The outer boots and webbing do not become an obstacle when the passenger gets on and off the vehicle.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. However, this idea is true. It is not limited to examples only.

[0011] 1 to 3 show the entire seatbelt device 1 and its main parts. Seat belt equipment The webbing 6 is of the three-point type, and one end of the webbing 6 is connected to the center as in the past. Anchor placed near the bottom of the tapilla 40 (placed inside the outer boot 4) through anchor fixed to the upper part of the center pillar 40 3, the other end is attached to the winding device 2 (retractor), and the A tongue plate is attached to the webbing 6 between the outer boot 4 and the through anchor 3. 5 is inserted. Attach this tongue plate 5 to the vehicle body member in the center of the vehicle. the buckle 7.

0012 The outer boot 4 is held so as to be able to swing freely in the longitudinal direction of the vehicle body around a swing shaft 8. Ru. A tension spring 9 is attached to the lower end of the swing shaft 8 in the outer boot 4. One end of a first flexible wire 15 is attached. The tension spring 9 is The outer boot 4 is biased counterclockwise in FIG. 5 rotates the outer boot 4 clockwise against the tensile force of the tension spring 9. Rotatably mounted. Note that the wire in this example does not necessarily have flexibility in its entirety. It is sufficient that only the part that requires deformation can be bent appropriately, for example, a wire rod , or a chain-like structure made of carbon fiber or other synthetic resin. Use string-like members and those connected to rod members with appropriate rigidity. can be used.

[0013] The other end of the wire 15 is connected to the sheet 10 via the first roller 13 supported by the vehicle body. It is attached to the seat part 11. Therefore, the seat 10 is positioned forward (in the direction of arrow A). direction), the wire rod 15 is sent backward via the first roller 13. As the outer boot 4 sag, the outer boot 4 is pulled by the counterclockwise biasing force of the tension spring 9. When the sheet 10 tilts forward (in the direction of arrow a) and moves backward (in the direction of arrow B), the wire 1 5, the outer boot 4 is pulled in a direction that reduces the forward tilt angle (in the direction of arrow b) direction). In this way, as the seat moves back and forth, the tip of the outer boot 4 By interlocking the parts in the same direction as the sheet 4, the webbing 6 device can be easily moved. I can do it accurately.

[0014] As shown in FIG. 2, a flexible sleeve 17 is provided approximately in the middle of the wire 15. is attached to the sleeve 17, and a ring-shaped link that can be slid on the sleeve 17 is attached. A connecting member 18 and a guide frame 19 are attached. This connecting member 18 is connected to the second line. Materials 16 are connected. The wire rod 16 is attached to the guide slot at the upper end of the guide frame 19. The upper end is fixed to the seat back 12 via the second roller 14 through the tube 26. Ru. Note that the guide frame 19 is fixed to the sheet 10, and the wire rod 16 is fixed to the second rod. It is arranged so as to be in contact with the right side of the controller 14 in the figure.

[0015] Therefore, for example, when getting on or off the rear seat, the seat back 12 is tilted forward (arrow C), the wire rod 16 is pulled upward, and as shown in FIG. 15 is pulled forward. As a result, the outer boot 4 aligns with the center pillar 40. It can rise up to a certain extent (in the direction of arrow c). In addition, this pull Shiro is For example, it can be set appropriately depending on the size of the radius of the second roller 14, etc.

[0016] The present invention is not limited to the above-mentioned embodiments; for example, as shown in FIGS. 4 to 6, Can be configured. This embodiment basically differs from the previous embodiments in that the swing shaft 8 of the outer boot 4 The attachment positions of the tension spring 9 and the first wire rod 15 are reversed, and The absence of the first roller 13 and the contact position of the second wire 16 with respect to the second roller 14 is the opposite. What is caused by this difference is that in the case of this embodiment, the movement of the wire 15 is The direction of movement and the direction of movement of the tip of the outer boot are the same, and the seat back 12 does not stand up. In this state, the wire rod 16 is pulled upward as shown in FIG. Members illustrated with the same reference numerals as in the previous embodiment are the same constituent elements, and their explanations will be omitted.

[0017] Therefore, when moving the sheet 10 back and forth, the wire rod 15 is bent. Since it moves, the guide frame 35 is made rectangular in order to make the movement smooth, and the connecting member is 18 is pulled downward by an auxiliary spring 37. In addition, the auxiliary spring 37, the connecting member 18 is guided so as to be movable only in the vertical direction. Alternatively, the lower part of the wire 16 may have a rod shape with appropriate rigidity. It can also be used as a member.

[0018] In addition, in the case of this embodiment, the seat back 12 is tilted forward (arrow (tilting in the direction of mark C), the wire rod 16 that was pulling the wire rod 15 moves downward, As shown in FIG. 6, the wire 15 returns to a straight line. As a result, the outer boots 4 are It is possible to rise up significantly along the center pillar 40 (in the direction of arrow c). Na As in the previous embodiment, this pulling margin is determined by, for example, the radius of the second roller 14. etc., it can be set appropriately.

[0019] In each of the embodiments described above, the outer boot 4 has an anchor attached to the flow part. However, the present invention is not limited to this configuration, and can also be applied to retractors, for example. The structure may be such that it is attached to the floor part and covered. In addition, in this invention, the outer boot 4 is naturally located on the door side, but it is placed on the front side. The above wires can be installed on either side of the seat, on the left or right, or in the middle. You can.

[0020]

[Effect of the idea]

As described above, according to the present invention, the outer boot is sealed by the first wire. The tip of the outer boot is connected to the seat part of the outer boot in the same direction as the seat movement direction. When you put on the webbing, the parts move together (movement in forward leaning and standing upright directions). The tip of the webbing can always be positioned at the appropriate position near the rear side of the seat, making it easier to pull the webbing. The extraction operation becomes easier. Furthermore, it can hold the webbing in a position where it is easy to wear. This prevents sagging or twisting when the webbing is attached. It becomes.

[0021] Further, a second wire is slidably connected to the first wire, and the other end is connected to the shaft. Due to the structure fixed to the seatback, the second wire is moved as the seatback rotates. The first wire can be pulled. The pulling action or pulling of this first wire The outer boots can be operated upright by the return operation. The outer boots can be moved to be stored on the center pillar side, allowing passengers to sit in the rear seats. The outer boots and webbing do not become an obstacle when climbing down. Therefore, in the seat belt device, the operability when wearing the webbing is improved. It is possible to simultaneously achieve improvements in the performance of getting on and off the vehicle for passengers in the rear seats.
