DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] A soft pillow is a soft support component that is attached to a vehicle seat. It can provide additional support and improve the riding experience of a relatively hard seat. The traditional way to install a soft pillow is to set a fixing belt on each side of the soft pillow. The two fixing belts are directly wrapped around the headrest of the seat from the left and right direction or the top and bottom direction and fixed to each other. However, since the headrest generally has a smooth surface, whether it is installed around the left and right or up and down, the soft pillow is easy to gradually slide down to the bottom of the headrest along the direction of gravity during use, affecting the user experience.

[0024] The vehicle seat assembly and the vehicle provided by the utility model are described in detail below in conjunction with the embodiments.

[0025] See also Figures 1 to 3 , Figure 1 It is a structural schematic diagram of an embodiment of a vehicle seat assembly of the present application; Figure 2 This is a schematic structural diagram of an embodiment of a soft pillow of the present application; Figure 3 1 is a schematic diagram of the structure of an embodiment of a seat of the present application. The present application proposes a vehicle seat assembly 100. The vehicle seat assembly 100 includes a seat 1, a soft pillow 2 and a limiting belt 11. The soft pillow 2 can be made of a material that is softer than the seat 1. The limiting belt 11 is arranged on the seat 1. Both ends of the limiting belt 11 are fixed relative to the seat 1. The limiting belt 11 can move away from the side of the seat 1 to form a mounting cavity that passes through the seat 1 along the first direction X. The first direction X is parallel to the side of the soft pillow 2 facing the seat 1. The first direction X can be perpendicular to the extension length direction of the limiting belt 11. When the seat 1 is provided with a headrest, the limiting belt 11 can be fixedly arranged with the headrest to form a mounting cavity, and the soft pillow 2 is used to support the head and neck. The limiting belt 11 can also be arranged near the corresponding waist of the seat 1, and the soft pillow 2 is used to support the waist. The soft pillow 2 is provided with a first mounting belt 21. The first mounting belt 21 includes a first fixed end 211 and a first movable end 212 that are opposite. A first fixing member 2121 is provided at the first movable end 212. The first fixed end 211 is connected to the soft pillow 2. The first movable end 212 can move relative to the soft pillow 2. The first movable end 212 passes through along the first direction X and is exposed outside the installation cavity, and the first fixing member 2121 is detachably connected to the soft pillow 2.

[0026] Specifically, the first fixing member 2121 and the soft pillow 2 can be directly connected or indirectly connected. When the first fixing member 2121 of the first movable end 212 is directly or indirectly connected to the soft pillow 2, the first movable end 212 and the soft pillow 2 are closed, and the first mounting belt 21 and the limiting belt 11 are mutually limited and cannot be separated. When the first fixing member 2121 of the first movable end 212 is disconnected from the soft pillow 2, the first movable end 212 and the soft pillow 2 are open, and the first mounting belt 21 can be separated from the limiting belt 11.

[0027] Along the direction from the soft pillow 2 to the seat 1, the orthographic projection of the first movable end 212 on the seat 1 and the orthographic projection of the limiting belt 11 on the seat 1 at least partially do not overlap. The direction from the soft pillow 2 to the seat 1 refers to the direction in which the soft pillow 2 points to the seat 1 and is perpendicular to the two sides when the side of the soft pillow 2 facing the seat 1 and the side of the seat 1 facing the soft pillow 2 are parallel to each other. When the first movable end 212 passes through the limiting belt 11, at least part of the first movable end 212 is not between the limiting belt 11 and the seat 1, that is, at least part of the first movable end 212 is exposed from the limiting belt 11.

[0028] Through the above arrangement, when the soft pillow 2 is installed on the seat 1 by passing the first mounting belt 21 through the limiting belt 11, the first mounting belt 21 is limited in the mounting cavity, so that the soft pillow 2 cannot continue to slide down even under the action of external forces such as gravity, and the soft pillow 2 is not easy to slide out of the appropriate supporting position range, and the supporting effect is stable.

[0029] Furthermore, the first movable end 212 of the first mounting belt 21 is exposed to the limiting belt 11, so that the first movable end 212 is subjected to less clamping force between the limiting belt 11 and the seat 1 when being disassembled, and is not easily obscured by the limiting belt 11 to interfere with the disassembly operation, making it more convenient to disassemble and assemble the soft pillow 2.

[0030] The specific method of connecting the first movable end 212 to the soft pillow 2 can be set as needed.

[0031] As in a specific embodiment, the soft pillow 2 also includes a second mounting belt 22. The second mounting belt 22 includes a second fixed end 221 and a second movable end 222. The second fixed end 221 is connected to the soft pillow 2. The first fixed end 211 and the second fixed end 221 are located on both sides of the limiting belt 11 along the first direction X. The first fixed end 211 and the second fixed end 221 can be aligned along the first direction X. The extension directions of the first mounting belt 21 and the second mounting belt 22 can be set to be the same. A second fixing piece 2221 is provided at the second movable end 222, and the first fixing piece 2121 and the second fixing piece 2221 are detachably connected.

[0032] Through the above arrangement, the second movable end 222 of the second mounting belt 22 can also move freely relative to the soft pillow 2. When the soft pillow 2 is installed, due to the narrow space between the soft pillow 2 and the seat 1, the first movable end 212 and the second movable end 222 can be pulled to positions that are easy to operate and then connected to each other. It is not difficult to operate due to the narrow space between the limiting belt 11 and the seat 1, and disassembly and assembly are convenient.

[0033] The first fixing member 2121 of the first movable end 212 and the second fixing member 2221 of the second movable end 222 can be connected to each other by mutual snap connection, Velcro bonding, screw connection, snap connection, direct tying, etc., as long as the first mounting belt 21 is connected to the second mounting belt 22, and there is no limitation here.

[0034] The extension length of the first mounting belt 21 may be the same as that of the second mounting belt 22, or may be different from that of the second mounting belt 22. In a specific embodiment, the soft pillow 2 has a center line a. The center line a separates the soft pillow 2 into two mirror-image parts of equal length along the first direction X. The first mounting belt 21 and the second mounting belt 22 have the same extension length. The connection between the first movable end 212 and the second movable end 222 is located on the center line a. The limiting belt 11 is eccentrically arranged on the seat 1 relative to the center line a, so that the orthographic projection of the first movable end 212 on the seat 1 along the direction from the soft pillow 2 to the seat 1 does not overlap with the orthographic projection of the limiting belt 11 on the seat 1 at least partially.

[0035] As in another specific embodiment, the soft pillow 2 has a center line a. The center line a divides the soft pillow 2 into two mirror-image parts of equal length along the first direction X. Along the first direction X, the length of the first mounting belt 21 is greater than the length of the second mounting belt 22. The length of the first mounting belt 21 is greater than half the length of the soft pillow 2 along the first direction X. The connection between the first movable end 212 and the second movable end 222 is located on one side of the center line a. The limiting belt 11 is arranged on the seat 1 along the center line a. Among the connections between the first movable end 212 and the second movable end 222, the distance from the point farthest from the center line a to the center line a is greater than the distance from the edge of the limiting belt 11 along the first direction X to the center line a.

[0036] Through the above arrangement, since the first mounting belt 21 and the second mounting belt 22 are of different lengths, the connection between the first movable end 212 and the second movable end 222 can be naturally located on one side of the limiting belt 11. When installing the soft pillow 2, it is not difficult to operate due to the narrow space between the limiting belt 11 and the seat 1. It is convenient for disassembly and assembly, and the limiting belt 11 does not have to be set on the seat 1 away from the center line a. The vehicle seat assembly 100 is more symmetrical and beautiful.

[0037] In one embodiment, the first fixing member 2121 extends from the first movable end 212 to the first fixed end 211. The second fixing member 2221 extends from the second movable end 222 to the second fixed end 221. Along the direction from the soft pillow 2 to the seat 1, the orthographic projections of the first fixing member 2121 and the second fixing member 2221 on the seat 1 do not overlap with the orthographic projections of the limiting belt 11 on the seat 1 at least partially.

[0038] Through the above arrangement, the first fixing member 2121 and the second fixing member 2221 can be simply connected to fix the first mounting belt 21 and the second mounting belt 22, and the first fixing member 2121 and the second fixing member 2221 are at least partially exposed from the limiting belt 11, are not easily affected by the narrow space, have fewer operation steps, and are easy to install.

[0039] In one embodiment, one of the first fixing member 2121 and the second fixing member 2221 is disposed away from the soft pillow 2, and the other is disposed toward the soft pillow 2. When the first fixing member 2121 and the second fixing member 2221 are detachably connected, the first fixing member 2121 or the second fixing member 2221 facing away from the soft pillow 2 is completely covered by the second mounting belt 22 or the first mounting belt 21. When the first fixing member 2121 faces away from the soft pillow 2, the first fixing member 2121 is covered between the second movable end 222 and the first movable end 212 and is not exposed. When the second fixing member 2221 faces away from the soft pillow 2, the second fixing member 2221 is covered between the first movable end 212 and the second movable end 222 and is not exposed.

[0040] Through the above arrangement, since the soft pillow 2 is close to the passenger when in use, when the soft pillow 2 is installed to the seat 1, the first fixing member 2121 or the second fixing member 2221 facing away from the soft pillow 2 is not exposed, and the first fixing member 2121 or the second fixing member 2221 is not easily accidentally connected with other objects such as hair and clothes in the outside world, and the vehicle seat assembly 100 has a good user experience.

[0041] In one embodiment, along a second direction Y perpendicular to the first direction X, the width of the first mounting belt 21 is greater than or equal to half the width of the soft pillow 2. The second direction Y is a direction parallel to the soft pillow 2 facing the side of the seat 1 and perpendicular to the first direction X, that is, the width direction of the soft pillow 2.

[0042] Through the above arrangement, a wider surface support is formed between the first mounting belt 21 and the limiting belt 11, and the friction force is greater. After the soft pillow 2 is installed on the seat 1, it is not easy to shake and slide, and the support is more stable.

[0043] In one embodiment, along the first direction X, the connection positions of the first fixed end 211 and the second fixed end 221 with the soft pillow 2 do not exceed the edge of the soft pillow 2 facing the seat 1. That is, when viewed from the side of the soft pillow 2 away from the seat 1 toward the seat 1, the first fixed end 211 and the second fixed end 221 are hidden between the soft pillow 2 and the seat 1 and are not exposed.

[0044] Through the above arrangement, when the soft pillow 2 is installed on the seat 1, the first mounting strap 21 and the second fixed end 221 are both hidden between the soft pillow 2 and the seat 1, and the first mounting strap 21 and the second fixed end 221 are not likely to be accidentally pulled during use. The vehicle seat assembly 100 is stably installed, and the first mounting strap 21 and the second fixed end 221 are not easily observed from the outside of the soft pillow 2, making the vehicle seat assembly 100 more refined and beautiful.

[0045] Furthermore, along the direction from the soft pillow 2 to the seat 1 , the orthographic projections of the first fixed end 211 and the second fixed end 221 on the seat 1 do not overlap with the orthographic projections of the limiting belt 11 on the seat 1 .

[0046] In one embodiment, one side of the seat 1 is used to support the occupant, and the limiting belt 11 is provided on the seat 1 to support the occupant. Therefore, the limiting belt 11 is also hidden between the soft pillow 2 and the seat 1, and the limiting belt 11 is not easy to be accidentally pulled during use, and the installation is stable. When observing from the front outside of the soft pillow 2, only the soft pillow 2 and the seat 1 can be observed, and the connection structure between the soft pillow 2 and the seat 1 can be well hidden, and the vehicle seat assembly 100 is more beautiful.

[0047] In one embodiment, a second fixing member 2221 is provided on the side of the soft pillow 2 facing the seat 1. Along the first direction, the first fixing end 211 and the first fixing member 2121 are spaced apart at opposite ends of the soft pillow 2. The length of the first mounting belt 21 is greater than half the length of the soft pillow 2. When the first movable end 212 passes through along the first direction and is exposed in the mounting cavity, the first fixing member 2121 is detachably connected to the second fixing member 2221, and the first movable end 212 completely covers the second fixing member 2221.

[0048] Through the above arrangement, the first mounting belt 21 is directly mounted on the soft pillow 2, the structure of the soft pillow 2 is streamlined, and the second fixing part 2221 on the soft pillow 2 can be completely covered by the first movable end 212 of the first mounting belt 21. When the soft pillow 2 is installed, the second fixing part 2221 will not be exposed, and is not easy to be accidentally connected with external hair, clothes, etc., and the user experience is good.

[0049] The installation direction of the soft pillow 2 and the limiting belt 11 can be installed along the vehicle height direction, can be installed in the horizontal direction, or can even be installed at an angle. The vehicle height direction refers to the direction from the roof to the bottom of the vehicle. In one embodiment, the limiting belt 11 extends along the vehicle height direction. The opposite ends of the limiting belt 11 do not exceed the opposite sides of the seat 1 along the vehicle height direction. The first direction X is perpendicular to the vehicle height direction. That is, the first installation belt 21 and the second installation belt 22 of the soft pillow 2 extend horizontally from left to right.

[0050] Through the above arrangement, the installation cavity of the limiting belt 11 limits the soft pillow 2 along the height direction of the vehicle, the soft pillow 2 is not easy to slide up and down in a large range, the support is stable, and the installation direction of the first installation belt 21 of the soft pillow 2 is horizontal, which is easy to operate from both sides of the seat 1 with both hands, and the installation is convenient.

[0051] In another embodiment, the limiting belt 11 extends in a direction perpendicular to the height of the vehicle. The opposite ends of the limiting belt 11 do not exceed the opposite sides of the seat 1 in a direction parallel to the height of the vehicle. The first direction X is parallel to the height of the vehicle. That is, the first mounting belt 21 and the second mounting belt 22 of the soft pillow 2 extend vertically up and down.

[0052] Through the above arrangement, the installation cavity of the limiting belt 11 limits the soft pillow 2 in the horizontal direction, and the soft pillow 2 is not easy to slide left and right, and the support is stable. In addition, since the soft pillow 2 is generally installed with a poor field of vision, the first adjustment belt may be affected by gravity and deviate up and down when passing through the limiting belt 11, while the first installation belt 21 is installed vertically, and the installation direction can be the same as the height direction of the vehicle. The first adjustment belt is not easily tilted by gravity when positioned, and positioning is convenient.

[0053] Please continue reading Figures 1 to 3 The present application provides a vehicle, including the vehicle seat assembly 100 as described above. The soft pillow 2 can be fixed on the seat 1. When the seat 1 has a headrest, the vehicle soft pillow 2 can be fixed on the side of the headrest facing the passenger. Through the above arrangement, the soft pillow 2 can enhance the riding comfort of the seat 1, and is easy to disassemble and assemble, and is not easy to slide, which is conducive to enhancing the riding comfort of the vehicle.
