Detailed Description

While the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that these are to be considered as examples of the invention and are not intended to limit the invention to the specific embodiments illustrated.

The vehicles referred to in the following embodiments may be standard gasoline powered vehicles, hybrid vehicles, electric vehicles, fuel cell vehicles, two or three wheeled vehicles, watercraft, aircraft, and/or any other type of vehicle. Vehicles include mobility-related components such as engines, electric motors, transmissions, suspensions, drive shafts and/or wheels, among others. The vehicle also includes components related to vehicle control, such as a vehicle controller, a vehicle bus, etc., through which the vehicle controller may interface with the in-vehicle components to effect control of these components. The vehicle may be non-autonomous, semi-autonomous (e.g., some conventional motor functions are controlled by the vehicle), or autonomous (e.g., motor functions are controlled by the vehicle without direct driver input).

As mentioned in the background art above, the inventors of the present invention have realized that, in the solutions in the prior art, the movable space of the webbing along the length direction of the through hole is small, the adjustability is poor, which makes it difficult for the webbing to fit well to the body of different passengers, and thus causes the passenger comfort to deteriorate.

Specifically, the optimum position of the webbing in the direction of the through-hole is different for different body sizes of passengers. The webbing at a specific position in the direction of the through-hole may be closer to the neck of the occupant to cause discomfort in that the neck is strangled for some occupants (for example, heavy occupants), and may be closer to the shoulder edge of the occupant or even slip off the shoulder for other occupants (for example, light occupants). Therefore, poor adjustability of the webbing along the length of the through-hole will result in the webbing failing to meet the comfort requirements of different occupants with respect to wearing the belt.

In addition, the small space in which the webbing is movable along the length of the through-hole also causes the edge of the webbing to rub against the guide, which tends to produce a "squeak" noise and thus disturb the occupant, which affects the riding environment.

Based on the problems in the prior art, the inventors of the present application provide in one or more embodiments a webbing guide device and a vehicle including the same, in order to solve the problems in the prior art.

Fig. 1 and 2 respectively show schematic views of different viewing angles of a belt webbing guide device 100 according to an embodiment of the present invention. Referring to fig. 1 and 2, the webbing guide device 100 includes a mounting member 10 and an adjusting member 20. The mounting member 10 defines a first surface 11 and a second surface 13 facing away from each other, and the mounting member 10 is provided with a mounting hole 15 extending through the first surface 11 and the second surface 13. The adjusting member 20 is slidably provided to the mounting member 10 and is provided with a through hole 26 for passing the webbing 200 therethrough, a projection of the through hole 26 on the first surface 11 is at least partially located in the mounting hole 15, and a sliding direction a of the adjusting member 20 is the same as an extending direction B of the through hole 26. The mount 10 may be mounted to a trim panel of a vehicle. The adjusting member 20 is slidable relative to the mounting member 10 in the same direction a as the extending direction B of the through-hole 26 so that the through-hole 26 of the adjusting member 20 can be moved in the extending direction B of the through-hole 26 to adjust the position, and the webbing 200 passing through the through-hole 26 can be adjusted accordingly in the extending direction B of the through-hole 26 to meet the use requirements of different occupants, so that the webbing 200 can be adjusted to a suitable position when the occupants use the webbing, for example, so that the webbing 200 is substantially centered on the shoulders of the occupants in the use state. In addition, the seat belt webbing 200 can be adjusted to a position where a proper gap is left between the seat belt webbing 200 and the hole wall of the through hole 26, and abnormal sound caused by friction between the edge of the seat belt webbing 200 and the hole wall of the through hole 26 is avoided.

The projection of the through hole 26 on the first surface 11 is at least partially located in the mounting hole 15, i.e. a part of the through hole 26 or the entire through hole 26 of the adjusting member 20 may be located in the mounting hole 15, or the through hole 26 of the adjusting member 20 and the mounting hole 15 directly face each other or partially coincide with each other in a direction perpendicular to the first surface 11. This ensures that the webbing 200 passing through the through-hole 26 can pass through the mounting hole 15 smoothly, preventing the mounting member 10 from obstructing the passage of the webbing 200 by blocking the through-hole 26. The extension of the mounting hole 15 may be determined according to the desired range of adjustability of the webbing 200 to allow the webbing 200 at any position within the desired range of adjustability to pass smoothly through the mounting hole 15. The mounting hole 15 may be an elongated hole and the extension direction C of the mounting hole 15 is the same as the extension direction B of the through hole 26.

Referring to the embodiment shown in fig. 1 and 2, the directions a, B, and C may be parallel to the width direction W of the vehicle. In other not shown embodiments, direction a, direction B and direction C may be parallel to each other and form an angle with direction W that may make the withdrawn seatbelt webbing more closely match the occupant's size. The angle can be adjusted by those skilled in the art to further increase comfort for passengers of different sizes.

When wearing the seat belt, the passenger can exert effort to the seat belt webbing 200 along the extending direction of through-hole 26 according to self demand, and under the effect of this effort, the seat belt webbing 200 contacts the pore wall of through-hole 26 one end and exerts the effort to the pore wall, and regulating part 20 can slide relative to installed part 10 under the effect of effort this moment, until regulating part 20 slides to suitable position, and suitable position is also adjusted to seat belt webbing 200 this moment.

Of course, in addition to the way of manual adjustment by the passenger, it is also possible to provide a way of automatic adjustment. The vehicle controller may acquire various information including the body shape information of the passenger and the position information of the adjusting member 20 with respect to the mounting member 10 and perform comprehensive judgment to determine the proper position of the adjusting member 20 and automatically control the adjusting member 20 to move to the proper position.

In an embodiment of the invention, the second surface 13 of the mounting part 10 is provided with a guide portion, so that a sliding fit between the adjusting part 20 and the mounting part 10 is achieved based on the guide portion. The guide portion may be in the form of a guide rail, a guide groove, or the like. The first surface 11 may be a front surface of the mounting member 10 and the second surface 13 may be a rear surface of the mounting member 10. By providing the guide portion on the second surface 13, the guide portion can be ensured to be out of the sight of the occupant, thereby ensuring an aesthetic appearance and good visibility of the webbing guide apparatus 100.

In some embodiments, the adjusting member 20 is a unitary structure and is slidably disposed on the guide portion. In other embodiments, the adjusting member 20 is a split structure and includes a sliding portion slidably disposed on the guiding portion and an adjusting portion connected to the sliding portion and having a through hole 26.

Referring to fig. 2, in the embodiment of the present invention, the guiding portion is a guiding groove 17 formed on the second surface 13, and the adjusting member 20 is slidable in the guiding groove 17. The guide groove 17 may be provided at both sides thereof with stoppers 19, for example, a plurality of hooks separately provided along the edge of the guide groove 17, and the stoppers 19 may function to prevent the adjusting member 20 from falling off the guide groove 17. The provision of the guide groove 17 in the second surface 13 such that the adjustment member 20 fits into the guide groove 17 facilitates reducing the overall thickness of the webbing guide 100, making the webbing guide 100 more compact. One end of the limiting member 19 is disposed outside the guide groove 17, and the other end thereof extends into the guide groove 17 to support the adjusting member 20. The stoppers 19 may be provided on the mounting member 10 by screwing, engaging, bonding, or the like.

With continued reference to fig. 1 and 2, in an embodiment of the present invention, the adjusting member 20 includes a body 22 and a protrusion 24 protruding from a surface of the body 22, a through hole 26 extends through at least a portion of the body 22 and the protrusion 24, and the protrusion 24 is located in the mounting hole 15. The projection 24 is movable within the mounting hole 15, and when the projection 24 is moved to such an extent that one end thereof abuts against the hole wall of the mounting hole 15, the projection 24 cannot be moved further forward, thereby defining the limit of movement of the adjuster 20. The protrusion 24 may be integrally formed with the body 22, or the protrusion 24 and the body 22 may be separately formed and then integrally connected.

In an embodiment of the present invention, referring to fig. 1, the top surface of the protrusion 24 may be flush with the first surface 11 and have a shape that matches (e.g., is similar to) the mounting hole 15, thereby providing a good sculpted surface. In other not shown embodiments, the top surface of the projection 24 may be slightly higher than the first surface 11, i.e., project slightly outward from the first surface 11, thereby further facilitating the passenger to apply force to the projection 24 to slide the adjuster 20, which may increase the convenience of operation.

The inventors of the present application have also recognized the problem of "seam(s)" in prior art solutions. In prior art solutions, the length of the through-hole of the guide is usually much greater than the width of the belt webbing to ensure that the belt can be pulled flexibly or that the belt webbing being pulled can be repositioned in conjunction with an additional belt positioning device, which can lead to a certain gap between the wall of the through-hole of the guide and the belt webbing through which the passenger's line of sight can pass and thus see the mechanical structures behind the guide, such as the belt webbing retractor, resulting in an unaesthetic appearance. One or more embodiments described below in this application may avoid or mitigate the problem of "gaps".

In the embodiment of the present invention, in the sliding process of the adjusting member 20, the adjusting member 20 always completely covers the mounting hole 15 except for the portion corresponding to the through hole 26. The presence of the mounting holes in the prior art makes it possible for the occupant's line of sight to see the mechanical structure behind the belt webbing guide through the mounting holes. The part of the mounting hole 15 except the part corresponding to the through hole 26 is covered by the adjusting piece 20, so that the gap formed by mounting can be shielded to the greatest extent on the basis of ensuring that the seat belt webbing 200 can smoothly pass through, and an aesthetic appearance surface is provided. The mounting hole 15 except for the portion corresponding to the through hole 26 may be: the mounting hole 15 is formed in a portion other than the through hole 26 or the projection of the through hole 26.

With reference to the following embodiments further proposed by the present application, it can be achieved that the adjusting member 20 always completely covers the mounting hole 15 except for the portion corresponding to the through hole 26 during the sliding of the adjusting member 20. Referring to fig. 1 and 2, the adjusting member 20 includes a middle portion 21 and two outer portions 23 located at both sides of the middle portion 21, a through hole 26 is formed in the middle portion 21, and the sum of the length of the middle portion 21 and the length of any one of the outer portions 23 is not less than the length of the mounting hole 15; the width of the adjusting piece 20 is not less than the width of the mounting hole 15.

The length of the adjustment member 20 may be the dimension of the adjustment member 20 in the direction B of extension of the through hole 26. During the sliding process of the adjusting member 20, the middle portion 21 or the projection thereof moves in the mounting hole 15, and since the sum of the length of the middle portion 21 and the length of any one of the outer portions 23 is not less than the length of the mounting hole 15, when the middle portion 21 or the projection thereof reaches the limit position of any one side in the mounting hole 15, the sum of the lengths of the outer portion 23 and the middle portion 21 positioned at the other side of the middle portion 21 is greater than the length of the mounting hole 15, so that the mounting hole 15 can be covered in the length direction. Meanwhile, since the width of the adjusting member 20 is not less than the width of the mounting hole 15, the adjusting member 20 may cover the mounting hole 15 in the width direction. In this way, the adjusting piece 20 can cover the mounting hole 15 except for the portion corresponding to the through-hole 26 in the length direction and the width direction regardless of the position to which the adjusting piece 20 is slid.

In some embodiments of the present invention, the mounting member 10 includes a base 12 and a side wall 14 connected to an edge of the base 12, the mounting hole 15 is formed in the base 12, the side wall 14 is provided with a fitting hole 16, the adjusting member 20 passes through the fitting hole 16, and the fitting hole 16 and the guide portion form a sliding path of the adjusting member 20. By providing the side wall 14, the structure and components provided on the back surface of the mounting member 10 can be shielded from the side, and the webbing guide device 100 can be prevented from being in the range of the view of the passenger, thereby further improving the problem of the gap. The side walls 14 may fit into a trim panel. The length of the adjusting member 20 is longer than that of the mounting member 10, so that the size of the mounting member 10 can be further reduced on the basis of ensuring that the adjusting member 20 covers the mounting hole 15. The fitting hole 16 is used for the adjusting member 20 to pass through, so as to prevent the side wall 14 from obstructing the sliding of the adjusting member 20, and the hole wall of the fitting hole 16 can also provide a certain function of supporting the adjusting member 20, so as to prevent the adjusting member 20 from falling off.

According to some embodiments of the present application, the through hole 26 is provided on the adjustment member 20 slidably fitted to the mounting member 10, and the length of the through hole 26 may be set shorter than in the prior art solution. In the prior art, the length of the through-hole of the belt outlet is slightly greater than the width of the belt webbing, with a difference typically in the range 10mm to 25 mm. In embodiments of the present invention, the difference between the length L1 of the through hole 26 and the width L2 of the webbing 200 may be less than 10mm, or even less than 5mm, for example in the range of 2mm to 3 mm. Thus, only a small gap remains between the wall of the through-hole 26 and the mounting strap 200, further reducing the likelihood of the occupant looking through the through-hole 26 to see the internal structure, and preventing the "gapping" problem. Referring to fig. 1 and 2, the through hole 26 may be a long hole extending straight, and both ends of the long hole naturally contract in a circular arc shape.

In some embodiments, the belt webbing guide apparatus 100 further includes a displacement sensor 40. The displacement sensor 40 is provided to the mounting member 10, and is configured to detect the displacement of the adjuster 20 and send the detection result to the vehicle controller. The vehicle controller can recognize the wearing state of the safety belt based on the displacement detection value of the adjusting member 20, and accordingly remind and correct the user to adjust the posture and correctly wear the safety belt, thereby improving the intelligent degree of the vehicle and increasing the use convenience.

The displacement sensor 40 may be any type of displacement sensor known in the art. Referring to fig. 2, the displacement sensor 40 may be disposed in the limiting member 19 and connected to the signal transmission line. The displacement sensor 40 can cooperate with the integrated circuit 30 to detect the displacement, and the integrated circuit 30 has a strip structure and extends in the same direction as the sliding direction of the adjusting member 20.

Referring to fig. 3 to 5, the present invention also proposes a vehicle comprising a trim panel 202 having an opening, a webbing retractor 204 disposed inside the trim panel 202, and the webbing guide 100 installed at the opening as described above. The webbing guide device 100 is provided outside the trim panel 202, and in the use state, the webbing 200 drawn out from the webbing take-up device 204 passes through the through-hole 26 of the adjuster 20 of the webbing guide device 100.

Through the technical scheme of the utility model, can increase the adjustable range of safety belt meshbelt along guider through-hole extending direction to guarantee that different passengers all can comfortably wear the safety belt, and can reduce the friction between safety belt meshbelt edge and the guider and send the risk of abnormal sound, can solve the problem in "gap" from the multi-aspect, guarantee the good outward appearance of guider, can also acquire the displacement value of regulating part in addition so that discernment safety belt wearing state and carry out intelligent control.
