[0027] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0028] Example 1
[0029] This embodiment provides a seat device that can be applied to a vehicle. The seat device can be a front seat or a rear seat. The seat device has the function of adjusting the reclining angle of the seat back 1 to meet the comfort requirements of the seat device. The following is a detailed description.
[0030] like Figures 1-4 As shown, the seat assembly includes a seat back 1, a seat cushion 2, and an adjustment component 3. The adjustment component 3 includes an adjustment bracket 31, a fixed bracket 32, and multiple angle adjusters. The fixed bracket 32 is connected to the seat cushion 2, and the adjustment bracket 31 is disposed between the fixed bracket 32 and the seat cushion 2. The two ends of the adjustment bracket 31 are connected to the seat back 1 and the fixed bracket 32 respectively through the angle adjusters, so that the seat back 1 can be adjusted to be flush with the seat cushion 2.
[0031] The seat backrest 1 includes a backrest frame (not shown in the figure) and a backrest 11, with the backrest 11 mounted on the backrest frame. Correspondingly, the seat cushion 2 includes a seat basin frame (not shown in the figure) and a seat cushion portion 21, with the seat cushion portion 21 mounted on the seat basin frame. The backrest frame and the seat basin frame are connected by an adjustment component 3, enabling the backrest frame to rotate relative to the seat basin frame.
[0032] When the seating arrangement is in normal use, the seat back 1 is connected to the adjustment bracket 31 via an adjuster. The seat back 1 can rotate relative to the adjustment bracket 31, while the adjustment bracket 31 remains stationary, thus allowing for angle adjustment of the seat back 1 to meet small-range angle requirements. The adjustment bracket 31 is connected to the fixed bracket 32 via another adjuster, and the fixed bracket 32 is connected to the seat cushion 2. The adjustment bracket 31 can rotate relative to the fixed bracket 32, thus meeting large-range angle requirements of the seat back 1. During the rotation adjustment of the adjustment bracket 31 relative to the fixed bracket 32, the seat back 1 can also rotate relative to the adjustment bracket 31. This allows the seat back 1 to be adjusted to be flush with the seat cushion 2, or one end of the seat back 1 to be flush with the seat cushion 2, while the other end is lower than the seat cushion 2. According to the actual application requirements of the seating arrangement, the reclining angle of the seating arrangement can be flexibly adjusted to meet the comfort requirements of the seating arrangement.
[0033] The adjusting bracket 31 is positioned between the fixed bracket 32 and the seat cushion 2. Both ends of the adjusting bracket 31 are connected to the seat back 1 and the fixed bracket 32 respectively via an angle adjuster. The method of setting the angle adjuster between the fixed bracket 32 and the adjusting bracket 31 enhances the structural strength of the angle adjuster installed on the fixed bracket 32 and reduces the probability of deformation and damage caused by excessive load on the angle adjuster. At the same time, with the angle adjuster installed between the fixed bracket 32 and the adjusting bracket 31, the seat back 1 and the adjusting component 3 can be transported and installed as a single structure, so that the seat back 1 can be used on different types of seat cushions 2, thus expanding the applicability of the seat back 1.
[0034] In one implementation, such as Figure 4 , Figure 5 As shown, adjustment brackets 31 are respectively provided on both sides of the seat back 1. The angle adjuster includes a first angle adjuster 33 and a second angle adjuster 34. Each adjustment bracket 31 is provided with a first angle adjuster 33 and a second angle adjuster 34. A first connecting rod 41 is provided between two opposite first angle adjusters 33, and a second connecting rod 42 is provided between two opposite second angle adjusters 34.
[0035] The first link 41 is located inside the seat back 1, and the second link 42 is located inside the seat cushion 2. The first adjusters 33 located on both sides of the seat back 1 can be adjusted synchronously via the first link 41, allowing the two first adjusters 33 to adjust in conjunction, which is convenient and ensures the synchronicity and stability of the adjustment of the two first adjusters 33. Similarly, the second adjusters 34 located on both sides of the seat back 1 can be adjusted synchronously via the second link 42, allowing the two second adjusters 34 to adjust in conjunction.
[0036] For example, the housing of the first angle adjuster 33 is connected to the fixed bracket 32 and the adjusting bracket 31 respectively; the housing of the second angle adjuster 34 is connected to the adjusting bracket 31 and the backrest frame respectively; the above connection method can be detachable or welded to meet the needs of installing and fixing the two angle adjusters.
[0037] In one embodiment, the second link 42 passes through the adjusting bracket 31 and is connected to the second angle adjuster 34.
[0038] Since the adjustment bracket 31 is located between the fixed bracket 32 and the seat cushion 2, the second link 42 is inserted into the adjustment bracket 31 to facilitate the connection between the end of the second link 42 and the second angle adjuster 34.
[0039] In one embodiment, the adjusting bracket 31 has a reinforcing part 35 located between the two angle adjusters.
[0040] The adjusting bracket 31 has a roughly long plate structure with rounded ends. Each end of the adjusting bracket 31 has an installation port for installing the angle adjuster. The middle part of the adjusting bracket 31 has a reinforcing part 35, which is bent to increase the structural strength of the adjusting bracket 31 and thus improve the stability of the two angle adjusters installed on the adjusting bracket 31.
[0041] For example, a gap 12 is provided between the seat back 1 and the seat cushion 2, and a reinforcing part 35 is provided corresponding to the gap 12. When the seat back 1 is rotated for adjustment, it does not interfere with the rotation of the seat cushion 2; the reinforcing part 35 corresponds to the gap 12 to ensure that the adjustment bracket 31 has sufficient structural strength, reducing the probability of deformation of the adjustment bracket 31, and the seat back 1 can be rotated and adjusted stably.
[0042] In one embodiment, the fixing bracket 32 is disposed at the end of the seat cushion 2.
[0043] The front end of the seat cushion 2 is the seating position, and the rear end of the seat cushion 2 is connected to the seat back 1 via the adjustment component 3. The fixed bracket 32 is set at the rear end of the seat cushion 2, which reduces the length of the adjustment bracket 31, improves the torsional resistance of the adjustment bracket 31 during rotation adjustment, and improves the structural strength of the adjustment bracket 31.
[0044] In one embodiment, the fixed bracket 32 includes a first fixed part 51 and a second fixed part 52, which are connected to form an included angle β. The first fixed part 51 is connected to the seat cushion 2, and the angle adjuster is connected to the second fixed part 52 and the adjusting bracket 31 respectively.
[0045] The fixed bracket 32 has an approximately L-shaped structure. The second fixed part 52 is spaced apart from the seat cushion 2, providing effective installation space for the adjustable bracket 31. At the same time, the first fixed part 51 and the second fixed part 52 are connected to form an included angle β, which strengthens the installation strength of the second adjuster 34 and further improves the installation stability of the second adjuster 34.
[0046] In one embodiment, a fixing seat 53 is provided at the bottom of the seat cushion 2. The fixing seat 53 has a fixing groove 54. One side wall of the fixing groove 54 is connected to the seat cushion 2, and the other side wall of the fixing groove 54 is connected to the first fixing part 51.
[0047] The fixing seat 53 has a fixing groove 54, which can strengthen the connection between the seat cushion 2 and the first fixing part 51. On the one hand, it can expand the installation space between the fixing bracket 32 and the seat cushion 2, and can effectively install the adjusting bracket 31; on the other hand, it can improve the stability of the adjusting bracket 31 and the fixing bracket 32 for installing the angle adjuster.
[0048] In one embodiment, the adjustment component 3 further includes an unlocker (not shown in the figure), which is connected to the angle adjuster and is used to control the angle adjuster to unlock.
[0049] The angle adjuster has a self-locking function, and the unlocker can be a manual unlocker or an electric unlocker. The manual unlocker can be a handle connected to the angle adjuster. Specifically, the first angle adjuster 33 and the second angle adjuster 34 are each equipped with a handle, and the unlocking action of the angle adjuster is achieved by manually controlling the handle. The electric unlocker can be a cable. One end of the cable is connected to the angle adjuster, and the other end of the cable is connected to a cable controller (not shown in the figure). The cable controller can electrically control the unlocking action of the angle adjuster. Specifically, one cable can connect to two first angle adjusters 33 at the same time, and another cable can connect to two second angle adjusters 34 at the same time. Each cable is connected to a different cable controller, so that different cable controllers can simultaneously control the unlocking of two corresponding angle adjusters.
