Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a seat for a vehicle. Background Technology

[0002] Vehicle seats are typically equipped with seat belts. In the event of a collision, seat belts restrain occupants to reduce injury. Seat belt systems may include webbing and buckles, with the buckles usually located in the seat cushion.

[0003] Some vehicles have height-adjustable seat cushions for their bench seats (e.g., the rear seats of a five-seater car). To ensure consistent external access to the seatbelt buckles, a recess is typically provided inside the seat cushion, with the opening of the recess on the seat surface and the seatbelt buckles retracted within it. However, when the seat cushion is raised, the seatbelt buckles do not rise with it, leaving the recess open. Foreign objects can then enter the recess, potentially causing seat malfunction. Summary of the Invention

[0004] To address the aforementioned technical problems, this application proposes a seat for a vehicle. The seat includes a seat cushion with a receiving space for accommodating a seatbelt buckle; the opening of the receiving space is located on the seat surface of the seat cushion; and a covering assembly including a cover plate; the cover plate is movably disposed within the receiving space. The seat cushion is adapted to move to a lowered state, with the seatbelt buckle located within the receiving space and the cover plate pushed open to expose it; and the seat cushion is adapted to move to a raised state, with the cover plate spaced apart from the seatbelt buckle, the cover plate closed and concealing the receiving space.

[0005] In one embodiment, the cover assembly further includes a housing adapted to be disposed within a receiving space, and a seatbelt buckle adapted to be received within the housing; and a cover plate is rotatably mounted on the housing.

[0006] In one embodiment, a stop protrusion extending toward the interior of the box is provided on the box body, and the cover plate abuts against the stop protrusion when it covers the receiving space.

[0007] In one embodiment, a pivot is connected between the cover plate and the housing; a first torsion spring is provided on the pivot, and the two ends of the first torsion spring abut against the cover plate and the housing respectively; when the seat cushion is in the lowered state, the first torsion spring is tensioned, and when the seat cushion is in the raised state, the first torsion spring is restored.

[0008] In one embodiment, the circumferential sidewall of the housing includes a guide wall that corresponds to the front of the vehicle along the length of the vehicle; the inner surface of the guide wall is inclined toward the front of the vehicle in a direction from the interior of the receiving space toward the opening of the receiving space; and the inner surface of the guide wall is adapted to slidably contact the seat belt buckle during seat cushion movement.

[0009] In one embodiment, the circumferential sidewall of the housing includes a guide wall that corresponds to the front of the vehicle along the length of the vehicle; a guide rib is formed on the inner surface of the guide wall that is inclined toward the front of the vehicle in a direction from the interior of the receiving space toward the opening of the receiving space; and the guide rib is adapted to slidably contact the seat belt buckle during seat cushion movement.

[0010] In one embodiment, a flexible covering layer is provided on the guide rib, and the seat belt buckle is adapted to slidably contact the covering layer.

[0011] In one embodiment, the seat cushion includes an elastic member, within which a support member is disposed, and the housing is mounted on the support member.

[0012] In one embodiment, the seat cushion also includes a seat cushion frame, on which the housing is mounted.

[0013] In one embodiment, the seatbelt buckle includes a buckle bracket; a buckle body hinged to the buckle bracket via a hinge shaft; and a second torsion spring mounted at the hinge shaft; the two ends of the second torsion spring abut against the buckle bracket and the buckle body, respectively. When the seat cushion is in the lowered state, the buckle body is within the receiving space and pushes open the cover, and the second torsion spring is in a first tensioned state; and when the seat cushion is in the raised state, the buckle body is spaced apart from the cover, and the second torsion spring is in a second tensioned state; the tension of the second torsion spring in the first tensioned state is greater than the tension in the second tensioned state.

[0014] In one embodiment, the latch body is provided with a protrusion extending toward the latch bracket, and the protrusion is adapted to rotate with the rotation of the latch body; the latch bracket is provided with a stop step in the rotation path of the protrusion; wherein, when the second torsion spring is in a first tension state, the protrusion and the stop step are spaced apart; and when the second torsion spring is in a second tension state, the protrusion and the stop step are in contact.

[0015] The beneficial effects of this application are as follows: According to the technical solution of this application, when the seat cushion is in the lowered state, the seat belt buckle is exposed. The occupant can sit on the seat and easily insert the seat belt latch into the buckle. When the seat cushion is in the raised state, the seat belt buckle does not rise with the seat cushion, and the cover conceals the storage space. This prevents foreign objects from falling into the storage space, helping to avoid seat malfunctions. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In this application, the direction used for "forward" refers to the direction pointing towards the front of the vehicle along its length.

[0032] Figure 1 A vehicle 1 according to a first embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 is equipped with front seats 11 and rear seats 12. The height of the seat cushion 2 of the rear seat 12 can be adjusted according to actual conditions to improve passenger comfort.

[0033] The technical solution of this application will be described below using the rear seat 12 as an example.

[0034] Reference Figure 2a and Figure 3 The rear seat 12 includes a seat cushion 2 and a cover assembly 3. Of course, the rear seat 12 may also include a backrest 121, a seat belt buckle 4, and other seat belt assemblies that match the seat belt buckle 4 (e.g., seat belt latches, not shown in the figure).

[0035] Seat cushion 2 includes, for example, two seats. Seatbelt buckle 4 is generally located between the two seats. Seat cushion 2 is also provided with a receiving space 201 for accommodating the seatbelt buckle 4, and the opening of the receiving space 201 is located on the seat surface of seat cushion 2. In this application, the seat surface of seat cushion 2 refers to the surface of seat cushion 2 for occupant seating.

[0036] Reference Figure 3 and Figure 4The cover assembly 3 includes a housing 30 and two cover plates (i.e., a first cover plate 31 and a second cover plate 32) rotatably mounted on the housing 30. The housing 30 is installed within the receiving space 201. The first cover plate 31 and the second cover plate 32 are also located within the receiving space 201. In some cases, the cover assembly may not have a housing, and the cover plates may be directly mounted on the seat cushion. It should be understood that, depending on the actual situation, the number of cover plates may also be one, which will not be elaborated here. The first cover plate 31 is the same as the second cover plate 32. For simplicity, the technical solution of this application will be described below using the first cover plate 31 as an example.

[0037] The accommodating space 201 is generally elongated, and the box 30 is a cuboid shape that matches the shape of the accommodating space 201. In addition, the dimensions of the box 30 match the dimensions of the seat belt buckle 4 so that the seat belt buckle 4 can be housed within the box 30.

[0038] Reference Figures 4 to 6 The circumferential sidewalls of the box body 30 include a first side plate 301 and a second side plate 302 opposite to each other, and a third side plate 303 and a fourth side plate 304 opposite to each other. A first cover plate 31 is mounted on the box body 30 via a pivot 312. For example, the two ends of the pivot 312 are respectively mounted on the first side plate 301 and the second side plate 302, and the first cover plate 31 is located between the first side plate 301 and the second side plate 302.

[0039] When seat cushion 2 is in the lowered position (e.g., rear seat 12 is in the seat position), seat belt buckle 4 is inside housing 30 and the two covers are pushed open, thus exposing seat belt buckle 4 from inside housing 30 (e.g., Figure 2b and Figure 7 (As shown). Occupants can sit in the rear seat 12 and easily insert the seatbelt latch (not shown) into the seatbelt buckle 4. As the seat cushion 2 is gradually raised, the cover assembly 3 moves with the seat cushion 2, but the seatbelt buckle 4 does not move with the seat cushion 2. Thus, the seatbelt buckle 4 gradually moves away from the housing 30 and spaced apart from the two covers. Correspondingly, the two covers gradually close (as shown). Figure 8 As shown). When the seat cushion 2 moves to the raised state (e.g., the seat cushion 2 is raised to its extreme position), the seat belt buckle 4 is spaced apart from the two covers, the two covers are closed and cover the receiving space 201, and the seat belt buckle 4 is also covered by the two covers (e.g.). Figure 2c and Figure 9 (As shown). In this way, foreign objects will not fall into the receiving space 201 (or the box 30), which helps to prevent the rear seat 12 from malfunctioning.

[0040] Reference Figure 4 , Figure 5 and Figure 6A first torsion spring 311 is provided on the pivot 312, with its two ends abutting against the first cover plate 31 and the third side plate 303 of the housing 30, respectively. When the seat cushion 2 is in the lowered state, the first cover plate 31 is pushed open by the seat belt buckle 4, and the first torsion spring 311 is tensioned (the second cover plate 32 is also pushed open by the seat belt buckle 4 accordingly). When the seat cushion 2 is in the raised state, the first torsion spring 311 drives the first cover plate 31 to close, and the first torsion spring 311 returns to its original position (the second cover plate 32 is also closed by the corresponding first torsion spring), and the two covers cover the accommodating space 201. In other words, when the occupant raises the seat cushion 2, the first and second covers automatically close under the push of the corresponding first torsion springs, and the occupant does not need to pay special attention to the first and second covers, which simplifies the seat cushion raising operation.

[0041] like Figure 5 As shown, stop protrusions 305 extending toward the interior of the box body 30 are respectively provided on the first side plate 301 and the second side plate 302. When the first cover 31 is closed, the first cover 31 abuts against the stop protrusions 305. In this way, even if the first cover 31 is subjected to pressure toward the interior of the receiving space 201 (or the box body 30), the first cover 31 will not be further pressed toward the interior of the receiving space 201 (or the box body 30) under the support of the stop protrusions 305. This helps to prevent injury to the occupant and also helps to prevent the cover assembly 3 from being damaged by pressure.

[0042] For example Figure 5 As shown, the third side plate 303 of the housing 30 corresponds to the front of the vehicle along its length. Furthermore, the inner surface of the third side plate 303 (i.e., the surface of the third side plate facing the interior of the housing) slopes towards the front of the vehicle in a direction from the interior of the receiving space 201 toward the opening of the receiving space 201 (this direction is generally parallel to the height direction of the vehicle). Thus, the third side plate 303 forms a guide wall. (Refer to...) Figures 7 to 9 As the seat cushion 2 gradually rises, the inner surface of the third side panel 303 of the housing 30 slidably contacts the seat belt buckle 4 and gradually moves away from it. As the seat cushion 2 gradually descends, the seat belt buckle 4 is guided by the inner surface of the third side panel 303 of the housing 30 and gradually slides into the interior of the housing 30. This ensures smooth movement of both the seat cushion 2 and the seat belt buckle 4, providing a comfortable experience for the occupant. It should be understood that the angle formed by the inner surface of the third side panel and the vehicle's height direction can be determined based on actual conditions and is not limited here.

[0043] In one embodiment, guide ribs 306 are formed on the inner surface of the third side panel 303 facing the interior of the housing 30. The guide ribs 306 are inclined towards the front of the vehicle in a direction from the interior of the receiving space 201 toward the opening of the receiving space 201 (this direction is generally parallel to the height direction of the vehicle). During the raising and lowering of the seat cushion 2, the seatbelt buckle 4 slidably contacts the guide ribs 306. Because the contact area between the seatbelt buckle 4 and the guide ribs 306 is small, the movement resistance of the seat cushion 2 and the seatbelt buckle 4 is also small, resulting in smoother movement. In one embodiment, there may be multiple guide ribs, with the seatbelt buckle slidably contacting these guide ribs, which helps to stabilize the movement of the seat cushion and / or the seatbelt buckle.

[0044] In one embodiment, a flexible covering layer (not shown) is provided on the guide rib 306. The seat belt buckle 4 is slidably in contact with the covering layer, which helps to reduce frictional noise between the guide rib 306 and the seat belt buckle 4, thereby improving the sensory quality of the rear seat 12.

[0045] In one embodiment, the seat cushion 2 includes an elastic member (not shown). For example, the elastic member is made of foam material to give the seat cushion 2 good elasticity. A support member (not shown) is provided within the elastic member, and the housing 30 is mounted on the support member. This improves the stability of the covering assembly 3. For example, the support member is a steel wire disposed within the elastic member. Figure 5 As shown, a connecting protrusion 307 is provided on the outer surface of the box 30, and a groove 308 is constructed on the connecting protrusion 307. The steel wire is engaged in the groove 307.

[0046] In one embodiment, the seat cushion 2 further includes a seat cushion frame (not shown), on which an elastic member is disposed. The housing 30 may also be mounted on the seat cushion frame. For example, a steel wire (not shown) is provided on the seat cushion frame, the wire engaging within a groove 307 of a connecting protrusion 307 on the housing 30. It should be noted that the elastic members of both the seat cushion frame and the seat cushion are well known to those skilled in the art and will not be described in detail here.

[0047] like Figure 10 As shown, the seatbelt buckle 4 includes a buckle bracket 41, a buckle body 43, and a second torsion spring 42. The buckle bracket 41 is fixedly connected to the vehicle body. The buckle body 43 is hinged to the buckle bracket 41 via a hinge shaft 401. The second torsion spring 42 is installed at the hinge shaft 401, and both ends of the second torsion spring 42 abut against the buckle bracket 41 and the buckle body 43, respectively.

[0048] like Figure 7As shown, when the seat cushion 2 is in the lowered state, the latch body 43 is inside the housing 30 and in contact with the third side plate 303. The latch body 43 also pushes open the two cover plates. The latch body 43 forms a small first angle with the latch bracket 41, so that the second torsion spring 42 is in a first tension state. Figure 8 As shown, as the seat cushion 2 gradually rises, the third side plate 303 of the box body 30 gradually slides away from the locking body 43, and the locking body 43 gradually separates from the two cover plates (the two cover plates gradually close). The angle between the locking body 43 and the locking bracket 41 gradually increases, causing the tension of the second torsion spring 42 to gradually decrease. Figure 9 As shown, when the seat cushion 2 is in the raised state, the locking body 43 is spaced apart from the two cover plates, which are closed and cover the receiving space 201 (or the box 30). The angle between the locking body 43 and the locking bracket 41 increases to a second angle greater than the first angle, and the second torsion spring 42 is in a second tension state. The tension of the second torsion spring 42 in the first tension state is greater than that in the second tension state. When the seat cushion 2 moves from the raised state to the lowered state, the state changes of the second torsion spring 42 and the locking body 43 are opposite to those described above, and will not be repeated here.

[0049] For example Figure 10 As shown, the latch body 43 has a protrusion 433 extending toward the latch bracket 41, which is adapted to rotate with the latch body 43. The latch bracket 41 has a limiting step 411 and a stopping step 412 located in the rotation path of the protrusion 433. The protrusion 433 can reciprocate between the limiting step 411 and the stopping step 412 (i.e., the limiting step 411 and the stopping step 412 together define the maximum rotation angle range of the protrusion 433 or the latch body 43). When the seat cushion 2 is in the lowered state, the second torsion spring 42 is in the first tension state, and the protrusion 433 is spaced apart from the stopping step 412 (it should be noted that at this time, the protrusion 433 does not contact the limiting step 411). When the seat cushion 2 is in the raised state, the second torsion spring 42 is in the second tension state, and the protrusion 433 contacts the stopping step 412.

[0050] In some cases, when the seat cushion 2 is in the raised state, the latch body 43 remains aligned with the third side plate 303 of the housing 30 under the constraint of the stop step 412. In this way, when the seat cushion 2 is lowered, the latch body 43 can accurately contact the third side plate 303 of the housing 30, and then smoothly enter the housing 30 under the guidance of the third side plate 303 of the housing 30.
