Description

Technical Field

[0001] The present invention relates to a belt guide, and more particularly to a belt guide suitable for application to a location where the attachment and detachment of a belt are frequently performed.

Background Art

[0002] The belt guide according to the present application is not limited in its usage form, but as an example of a location where the attachment and detachment of a belt are frequently performed, one that guides the seat belt of a vehicle can be cited. In particular, a child seat called a junior seat, as disclosed in Patent Document 1, is designed to wrap the seat belt attached to the vehicle around the junior seat to adjust the belt height and hold the child's body, unlike a child seat for infants. For this reason, the belt guide for wrapping the seat belt is required to have characteristics such that the attachment and detachment of the belt are facilitated and the belt does not come off during use.

[0003] However, as shown in FIG. 5, the belt guide disclosed in Patent Document 1 has a configuration including a base portion 2, a first piece 3, and a second piece 4. In the belt guide 1 having such a basic configuration, the base portion 2 is an element constituting the lower side of the belt holding space 5, and the first piece 3 is an element extending from the proximal end side of the base portion 2 and constituting a part of the upper side of the belt holding space 5. Further, the second piece 4 is an element extending from the distal end side of the base portion 2 and constituting the other part of the upper side of the belt holding space 5. Furthermore, a gap (belt entry / exit space 6) for guiding the seat belt 50 into the belt holding space 5 is provided between the first piece 3 and the second piece 4.

[0004] The belt guide 1 having such a configuration satisfies the characteristic that the seat belt 50 is difficult to come off during use, but there is a concern that the attachment and detachment are troublesome. This is because the seat belt 50 inserted from the belt entry / exit space 6 is pushed into the lower space of the first piece 3 as shown by the arrow A, and then expanded into the lower space of the second piece 4 as shown by the arrow B, and then an operation of arranging it in the belt holding space 5 is required.

[0005] On the other hand, a belt guide that does not require a folding operation for guiding the seat belt 50 into the belt holding space 5 is disclosed in Patent Document 2. The belt guide disclosed in Patent Document 2 is a guide for positioning the shoulder belt of the seat backrest portion. The belt guide disclosed in Patent Document 2 includes a rotating portion by pin connection on one side of the lower end of the belt guide, an opening on the side of the pin arrangement position, and a belt receiving portion extending in a direction opposite to the pin and having an inclination in a direction away from the lower end. The belt receiving portion has a raised portion formed with an inclination opposite to that of the belt receiving portion. In the fixed state, the raised portion guides the belt to the belt receiving portion as a guide. On the other hand, when the belt guide is tilted with the pin as a base point, the inclination of the raised portion has a downward gradient toward the tip side, and the seat belt looped around the belt receiving portion will be detached along the raised portion. Thus, according to the belt guide disclosed in Patent Document 2, in the use state, the belt is difficult to come off and the attachment and detachment are facilitated.

[0006] However, the belt guide disclosed in Patent Document 2 is configured such that the width of the opening is wider than that of the belt receiving portion, and the width between the raised portion and the tip of the belt receiving portion is wider than that of the opening. For this reason, depending on the place of use, when a force is applied in the belt tension direction, the belt in the use state may be in a state where it is easily detached.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the belt guide according to the present invention will be described in detail with reference to the drawings. In the drawings, FIG. 1 is a side view of a belt guide according to an embodiment, and FIG. 2 is a plan view thereof. Further, FIG. 3 is a diagram for explaining a method of attaching and detaching a belt to and from a belt guide according to an embodiment, and FIG. 4 is a side view showing an example of a junior seat to which a belt guide according to an embodiment is attached.

[0016] [Configuration] In this embodiment, regarding the belt guide according to the invention, the belt guide 10 used for passing the waist belt (seat belt 50) of the junior seat 100 as shown in FIG. 4 will be described as an example. Note that the junior seat 100 shown in FIG. 4 is basically composed of a waist support portion 102, a backrest portion 104, and a head support portion 106. The waist support portion 102 of the junior seat 100 shown in FIG. 4 has no seat surface, and a child using the junior seat 100 sits directly on the vehicle seat 110, and the waist support portion 102 is arranged on the side surface of the waist. In the junior seat 100 having such a basic configuration, the belt guide according to the invention is arranged symmetrically in a pair at the tip of the waist support portion 102 (FIG. 4 is a side view).

[0017] The belt guide 10 according to this embodiment is composed of a first piece 12, a second piece 14, and a third piece 16 to form a belt holding space 18, a belt entry / exit space 20, and a folding space 22. In the following description, expressions such as "upper side" and "lower side" refer to the vertical relationship based on the belt guide 10 in the mounted state as shown in FIG. 1.

[0018] The first piece 12 is a belt support piece that covers the upper part of the belt holding space 18, the details of which will be described later, and constitutes the upper side of the belt holding space 18. The first piece 12 is configured such that the inner side 12a constituting the upper side of the belt holding space is flat, and the outer piece 12b located on the side opposite to the inner side 12a is arc-shaped and tapers. Further, at the tip, which is the intersection of the inner side 12a and the outer side 12b, R processing is performed to prevent damage to the seat belt 50 (belt) and improve slidability. Furthermore, the first piece 12 according to this embodiment has an inclined surface so as to taper also in a plan view as shown in FIG. 2. Therefore, it plays a so-called guiding role and can make the introduction of the seat belt 50 smooth.

[0019] The second piece 14 covers the lower part of the belt holding space 18 and is a belt support piece that constitutes the lower side of the belt holding space 18. The second piece 14 makes the inner side 14a that constitutes the lower side of the belt holding space 18 flat, and is configured to be tapered by making the arrangement angle of the outer side 14b located on the side opposite to the inner side 14a different from that of the inner side 14a and then making it flat. And a third piece 16 extends from the tip of the second piece 14. Note that the first piece 12 and the second piece 14 with such a configuration are connected by a fork portion 13 located at the innermost part of the belt holding space 18.

[0020] The third piece 16 is a belt guide piece for forming a belt entry / exit space 20 and a folding space 22 on the tip side of the belt holding space 18. The third piece 16 is arranged so as to form an acute-angle fold with the extension line L1 of the inner side 14a in the second piece 14 as a base point, thereby forming the folding space 22, and forming the belt entry / exit space 20 between it and the first piece 12.

[0021] Among the belt holding space 18, the belt inlet / outlet space 20, and the folding space 22 formed by the first piece 12, the second piece 14, and the third piece 16 with such a configuration, the belt holding space 18 is a space for holding the seat belt 50 in the use state, and is formed from the joint portion 13 formed by connecting the base end portions of the first piece 12 and the second piece 14 to the opening located on the tip side of both pieces. The belt holding space 18 with such a configuration has the inner side 12a of the first piece 12 and the inner side 14a of the second piece 14 configured to be substantially parallel. Further, the second piece 14 is formed wider toward the base end portion in side view. For this reason, the belt holding space 18 is provided with an inclination corresponding to the width change of the second piece from the opening to the joint portion. The belt inlet / outlet space 20 is provided between the outer side 12b of the first piece 12 and the third piece 16, and constitutes a belt inlet for guiding the seat belt 50 into the belt holding space 18. The folding space 22 is a space located between the longitudinal end portion of the belt holding space 18 and the longitudinal end portion of the belt inlet / outlet space 20, and constitutes a space in which the belt inlet / outlet space 20 and the belt holding space 18 are continuous via the folding space 22. The folding space 22 functions to reverse the direction of the seat belt 50 traveling between the belt holding space 18 and the belt inlet / outlet space 20. Here, each space formed in the belt guide 10 is configured to have a relationship of B > A > C when the width of the belt holding space 18 is A, the width of the folding space 22 is B, and the width of the belt inlet / outlet space 20 is C.

[0022] By providing the folding space 22 between the belt holding space 18 and the belt inlet / outlet space 20 to reverse the direction of the seat belt 50, it is possible to make it difficult for the seat belt 50 in the use state to be detached from the belt holding space 18. Further, by giving the widths of the respective spaces the above-described relationship, it is possible to improve the ease of wearing the seat belt 50 while preventing the seat belt 50 from being unintentionally detached.

[0023] [Operation and Effect] Next, with the belt guide 10 configured as described above attached to the waist support portion 102 of the junior seat 100, the procedure until the seat belt 50 is held in the belt holding space 18 will be described with reference to FIGS. 3(A) to 3(C). Note that the seat belt 50 shown in FIG. 3 shows the end face in the width direction of the belt. For the sake of explanation, the end portions in the width direction of the seat belt 50 are referred to as one end portion 50a and the other end portion 50b, respectively.

[0024] First, as shown in FIG. 3(A), with the seat belt 50 vertical (in a state where the other end portion 50b is slightly tilted toward the proximal end side of the first piece 12), the seat belt 50 is inserted into the belt entry / exit space 20 from the one end portion 50a side. Next, as shown in FIG. 3(B), the seat belt 50 is bent so as to be reversed in the folding space 22 and inserted into the belt holding space 18 from the one end portion 50a side of the seat belt 50. Then, as shown in FIG. 3(C), by pulling all of the seat belt 50 into the belt holding space 18, the attachment of the seat belt 50 to the belt guide 10 is completed.

[0025] When detaching the seat belt 50 from the belt guide 10, the seat belt 50 is shifted and reversed into the folding space 22 as shown in FIG. 3(B) from the other end portion 50b side of the seat belt 50. Then, by pulling up the seat belt 50 that has reached the belt entry / exit space 20 from the other end portion 50b side, the seat belt 50 can be detached from the belt guide 10 as shown in FIG. 3(A).

[0026] Thus, according to the belt guide 10 according to the present embodiment, the seat belt 50 can be inserted from one direction and guided to the belt holding space 18. Therefore, there is no need to fold the seat belt 50 in the narrow belt holding space 18, and the attachment and detachment of the seat belt 50 become easy. Further, since there is no need to fold the seat belt 50 in the belt holding space 18, the length of the belt holding space 18 can be shortened compared to the conventional case. For this reason, it is also possible to reduce the size of the belt guide 10 itself.

[0027] Further, by making the width B of the folding space 22 wider than the width A of the belt holding space 18, the foldability of the seat belt 50, that is, the ease of attachment and detachment, is improved. Furthermore, by making the width C of the belt entry / exit space 20 narrower than the width A of the belt holding space 18, it is possible to prevent the seat belt 50 from unintentionally detaching from the belt guide 10. Therefore, during use, it is difficult for the seat belt 50 to detach from the belt guide 10. Further, by making the arrangement angle between the belt entry / exit space 20 and the belt holding space 18 an acute angle, it is possible to achieve the above-described effects regardless of the attachment angle of the belt guide 10. Furthermore, when the seat belt 50 is pulled toward the first piece 12 side in the mounting state as shown in FIG. 3, due to the inclination of the belt holding space 18, a force that pulls one end portion 50a of the seat belt 50 toward the fork portion 13 side acts, so that it is possible to prevent the seat belt 50 from unintentionally detaching.

Industrial Applicability

[0028] In the above embodiment, it was described that the belt guide 10 is attached to the tip of the main part support portion 102 in the junior seat 100 and guides the waist belt. However, the belt guide 10 according to the present embodiment can also be used as an element for guiding a shoulder belt at other parts, for example, as disclosed in Patent Document 2.
