Description

Seatbelt deliverer and seat Technical Field

[0001] The present invention relates to safety devices for vehicles, and more specifically, to seat belt deliverers and seats including the seat belt deliverers. Background Technology

[0002] The vehicle is equipped with a variety of safety devices, such as airbags and seat belts.

[0003] Seat belts are used to restrain occupants in the event of a vehicle collision, thereby preventing occupants from secondary impacts with the steering wheel and dashboard, or from being ejected from the vehicle and suffering injury or death. Seat belts use webbing pulled from the seat belt retractor to restrain seated occupants, securing them to their seats and protecting them in the event of a collision.

[0004] To facilitate seatbelt fastening, a seatbelt deliverer is provided. The basic function of the seatbelt deliverer is to guide the seatbelt webbing from its concealed position to a more ergonomically accessible delivery position, simplifying the seatbelt fastening process. When the seatbelt unit is integrated into the vehicle seat backrest, the seatbelt deliverer is also located within the seat backrest, and the seatbelt webbing extends from the backrest and is grasped by the deliverer. When activated, the seatbelt deliverer moves the seatbelt webbing from its concealed position (approximately above and behind the occupant's shoulder) to its delivery position (approximately above and in front of the occupant's shoulder). Therefore, the occupant can grasp the seatbelt at the delivery position by moving their arm slightly above and in front of their shoulder. This delivery position provides an ergonomically convenient grip, avoiding the need to reach over the other shoulder to the concealed position, thus preventing extreme rotational movements of the upper body and shoulders.

[0005] Considering the various sitting postures of occupants, or the repeated force exerted by their shoulders against the back of the seat, which can lead to occupant injury or seat belt deliverer damage, it is desirable to provide a safe and durable seat belt deliverer. Summary of the Invention

[0023] The features, advantages, and technical effects of exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same symbols denote the same elements, wherein:

[0024] Figure 1 schematically illustrates a seatbelt delivery device in a first state according to an embodiment of the present invention.

[0025] Figure 2 schematically illustrates a seatbelt delivery device in a second state according to an embodiment of the present invention.

[0026] Figure 3 schematically shows some components of a seatbelt delivery device according to an embodiment of the present invention. Detailed Implementation

[0027] The following describes specific embodiments of the seatbelt delivery device and seat according to the present invention with reference to the accompanying drawings. The detailed description and drawings below are provided to illustrate the principles of the invention. The invention is not limited to the described preferred embodiments; the various embodiments described can be used individually or in any combination. The scope of protection of the invention is defined by the claims.

[0028] Furthermore, spatially related terms (such as "up," "down," "left," and "right") are used to describe the relative positional relationship between elements shown in the accompanying drawings and other elements. Therefore, spatially related terms can be applied to directions different from those shown in the accompanying drawings. Clearly, while all these spatially related terms refer to the directions shown in the accompanying drawings for ease of explanation, those skilled in the art will understand that directions different from those shown in the accompanying drawings can be used.

[0029] Figure 1 schematically illustrates a seatbelt delivery device in a first state according to an embodiment of the present invention. Figure 2 schematically illustrates a seatbelt delivery device in a second state according to an embodiment of the present invention. The seatbelt delivery device according to an embodiment of the present invention will be described below with reference to Figures 1 and 2.

[0030] As shown in Figures 1 and 2, the seat 1 of the present invention includes a seat belt deliverer 10 for use with a seat belt device in a motor vehicle. As shown in Figure 1, the seat belt webbing 2 extends from the rear side of the backrest of the seat 1, passes over the top of the backrest substantially close to it, and extends to the front side of the backrest. It is conceivable that when an occupant sits on the seat 1, the portion of the webbing 2 located on the front side of the backrest is substantially behind the occupant's upper body. In this case, when the occupant puts on the seat belt, they need to reach their left arm backward over their right shoulder and continue moving backward until they can reach the webbing 2; that is, the occupant's shoulder and upper body need to rotate at a large angle. To facilitate the occupant's gripping of the webbing 2, as shown in Figure 2, when the seatbelt delivery device 10 is activated, the orientation of a section of the webbing 2 located on the front side of the back changes from downward to forward and upward. By changing the orientation of this section of the webbing 2, that section will be approximately located on the upper front side of the occupant's shoulder. At this point, the occupant can grip the webbing 2 by moving their left arm to a position slightly above and in front of their right shoulder. The occupant no longer needs to rotate their upper body to grip the webbing 2, thus improving the ease of gripping the webbing 2. Therefore, the seatbelt delivery device of the present invention can guide the webbing of the seatbelt device from a hidden position to a delivery position that is more ergonomically easier to grip, thereby simplifying the process of wearing a seatbelt.

[0031] The structure and operation of the seat belt delivery device of the present invention will be described in detail below.

[0032] Referring again to Figures 1 and 2, the seatbelt device is installed on the backrest of the seat 1, and the webbing 2 extends from the retractor. The seatbelt delivery device 10 is also arranged on the backrest of the seat 1 and grasps the extended portion of the webbing 2.

[0033] The seatbelt delivery device 10 of the present invention includes a delivery arm and a transmission member 12 tractively connected to the delivery arm. The delivery arm has an actuating end 11, which has a first predetermined position P1 as shown in FIG. 1 and a second predetermined position P2 as shown in FIG. 2. The transmission member 12 transmits power from the drive member 13 to the delivery arm to drive the actuating end 11 to switch between the first predetermined position P1 and the second predetermined position P2. When the actuating end 11 is in the first predetermined position P1, the portion of the webbing 2 located on the front side of the backrest is oriented downward; when the actuating end 11 is in the second predetermined position P2, the portion of the webbing 2 located on the front side of the backrest extends forward and upward from the top of the backrest and then extends downward, thus changing the portion of the webbing 2 located on the front side of the backrest from extending downward (i.e., in the first extension direction) to extending forward and upward (i.e., in the second extension direction). In other words, when the actuator 11 switches from the first predetermined position P1 to the second predetermined position P2, a portion of the seat belt webbing 2 is oriented from the first extension direction to the second extension direction to facilitate the occupant to grab the webbing 2; when the actuator 11 switches from the second predetermined position P2 to the first predetermined position P1, a portion of the seat belt webbing 2 is oriented from the second extension direction to the first extension direction to hide the webbing 2 in the seat 1.

[0034] Figure 3 schematically illustrates some components of a seatbelt delivery device according to an embodiment of the present invention. The seatbelt delivery device according to an embodiment of the present invention will be described in detail below with reference to Figures 1, 2 and 3.

[0035] As shown in Figures 2 and 3, the delivery arm includes a linear member 14 and a guide member 15. The linear member 14 is flexible, and a portion of it is disposed within a tubular section 150 of the guide member 15. The linear member 14 is capable of moving freely within the inner cavity of the tubular section 150. Because the linear member 14 is elongated and flexible, it will not cause injury even if the occupant adopts various sitting postures, such as leaning their head against the delivery arm; furthermore, the linear member is not easily damaged even if the occupant's shoulders repeatedly exert force against the seat back. Therefore, the seatbelt delivery device of the present invention is safe and not easily damaged.

[0036] As shown in Figure 3, the guide 15 includes a first guide portion 151 and a second guide portion 152. Both the first guide portion 151 and the second guide portion 152 can be block-shaped components. To facilitate their cooperation, the first guide portion 151 includes a first shaped portion, and the second guide portion 152 includes a second shaped portion, with the first shaped portion and the second shaped portion engaging in shape. It should be noted that the second guide portion 152, as the actuating end 11, needs to switch between a first predetermined position P1 and a second predetermined position P2. Therefore, the shape cooperation between the first guide portion 151 and the second guide portion 152 ensures that the second guide portion 152 can be accurately and stably positioned at the first predetermined position P1. In the example shown, one end face of the first guide portion 151 has a groove; correspondingly, the second guide portion 152 may include a protrusion that engages with the groove. To ensure that the guide portion 15 has a flush mating end face at the first predetermined position P1, the second guide portion 152 can be configured such that its overall shape complements the groove shape of the first guide portion 151, that is, the shape and size of the second guide portion 152 are adapted to the groove. This is merely an example; the first guide portion 151 can be configured to have a protrusion, and correspondingly, the second guide portion 152 can be configured to have a groove. Furthermore, the guide member 15 can also have a flush end face formed after the protrusion is positioned into the groove.

[0037] Referring to Figures 1 and 2, the first guide portion 151 serves as a fastener fixed to the top of the backrest of the seat 1 and is fixed at a first predetermined position P1. The first guide portion 151 includes a through hole 1512 for the linear member 14 to pass through and a first opening slot 151 for the webbing 2 to pass through. One end of a tube segment 150 of the guide member 15 is fixed to the through hole 1512 of the first guide portion 151, and the tube segment 150 is aligned with the through hole 1512 so that the linear member 14 extends through both the tube segment 150 and the through hole 1512 and is then fixed to the second guide portion 152. A portion of the linear member 14 is positioned on the rear side of the backrest of the seat 1, and another portion is positioned on the top of the backrest of the seat 1. The first end (lower end in FIG. 1) of the linear member 14 is drivenly connected to the transmission member 12, and the second end (upper end in FIG. 1) of the linear member is fixed together with the second guide portion 152. Accordingly, the second guide portion 152 may also include a second opening groove 1521 for the webbing 2 to pass through. Specifically, the first end of the linear member 14 is drivenly connected to the transmission member 12, and the second end of the linear member 14 passes through the pipe section 150 and the through hole 1512 on the first guide portion 151, and is slidably connected to the webbing 2 at the operating end 11 (i.e., the second guide portion 152).

[0038] The transmission member 12 will now be described in detail. As shown in Figure 2, in this embodiment, the transmission member 12 includes two first transmission members 121 and one second transmission member 122. The two first transmission members 121 are respectively fixed at a first transmission position and a second transmission position (arranged one above the other in the figure), and the second transmission member 122 cooperates with the first transmission members 121. As shown, the second transmission member 122 is constructed as a ring, and the direction determined by the line connecting the first transmission position and the second transmission position is consistent with the predetermined movement path of the first end of the linear member 14. Thus, the section of the second transmission member 122 positioned between the two first transmission members 121 is also consistent with the predetermined movement path of the first end of the linear member 14. In this case, the end of the linear member 14 remains relatively stationary with respect to the second transmission member 122, and can receive power via the transmission member 12 in a simple transmission manner. In one example, the first transmission member 121 can be constructed as a pulley, and the second transmission member 122 can be constructed as a belt. Of course, this is just an example, and the transmission member can also be in the form of a gear and rack.

[0039] For this purpose, the seatbelt delivery device 10 also includes a slider 17 and a track 16. The slider 17 is provided with a first connecting portion for fixing to the second transmission member 122 and a second connecting portion for fixing to the first end of the linear member 14. In one example, the first and second connecting portions can be provided as screws to fix both the linear member 14 and the second transmission member 122 to the same component, namely the slider 17. The track 16 extends in the same direction as a predetermined movement path of the first end of the linear member 14. The slider 17 is slidable along the track 16, thereby slidably connecting the track 16 to the linear member 14, particularly at the first end of the linear member 14, while simultaneously defining the predetermined movement path of the first end of the linear member 14. Although the figure shows the track 16 located on the side of the slider 17 facing the backrest, this is just an example. The track 16 can also be positioned on the left and right sides of the slider 17, or even integrated into the frame of the backrest. Alternatively, the track can be replaced with other forms, such as a guide chamber. Furthermore, the connection between the second transmission member and the linear member is not limited to an indirect connection; the two can be directly connected together.

[0040] The driving component 13 is, for example, a motor. Referring to FIG1, when the motor starts and drives the second transmission component 122 to rotate counterclockwise, the sliding component 17, which is fixed to the second transmission component 122, moves upward; the linear component 14, which is also fixed to the sliding component 17, also moves upward together, thereby starting from the first predetermined position P1, passing through the pipe section 150 and the through hole 1512 of the first guide 151, and continuing to move until the second guide 152 is moved to the second predetermined position P2, at which point the motor stops driving the second transmission component 122. Similarly, referring to Figure 2, when the motor starts and drives the second transmission member 122 to rotate clockwise, the sliding member 17, which is fixed to the second transmission member 122, moves downward; the linear member 14, which is also fixed to the sliding member 17, also moves downward together, so that it continues to move from the second predetermined position P2, through the through hole 1512 of the first guide 151, through the pipe section 150, until the second guide 152 is moved to the first predetermined position P1, at which point the motor stops driving the second transmission member 122.

[0041] As mentioned above, although exemplary embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and the scope of protection of the present invention should be defined by the claims and their equivalents.
