One embodiment of a vehicle seat provided by the present application is shown in fig. 1 and includes a seat body 10 and seat side wings 20 located at the sides of the seat body 10. The seat body 10 includes a seat 11 and an adjustable backrest 12, wherein the adjustable backrest 12 is adjustable in a front-back direction between a first position and a second position relative to the seat side wings 20 or the seat 11; when the adjustable backrest 12 is at the first position, the adjustable backrest 12 and the chair seat 11 form an included angle of approximately 90 degrees, and no step or small gap exists between the adjustable backrest 12 and the chair side wings 20; when the adjustable backrest 12 is at the second position, the included angle between the adjustable backrest 12 and the seat 11 is greater than 90 °, and at this time, the step or gap between the adjustable backrest 12 and the seat side wing 20 is enlarged; in order to eliminate step differences or gaps between the adjustable backrest 12 and the seat side wings 20, the vehicle seat further comprises an adjustable trim structure 30, which adjustable trim structure 30 is mounted on the seat side wings 20 and serves to form a smooth transition zone when forming a step between the adjustable backrest 12 and the seat side wings 20. The adjustable trim structure 30 includes: the flexible decoration 31 is in a contraction position when the flexible decoration 31 is in a locking state under the action of the elastic locking part, so that a gap between the adjustable backrest 12 and the seat side wing 20 in the first position is eliminated, and smooth transition is realized between the adjustable backrest 12 and the seat side wing 20; when the flexible garnish 31 is in the unlocked state by the elastic locking portion, the flexible garnish 31 is in the extended position to eliminate a gap between the adjustable backrest 12 and the seat side flap 20 in the second position. The step difference or gap between the adjustable backrest 12 and the side wing can be eliminated through the structure, and articles can be prevented from falling into the gap between the adjustable backrest 12 and the seat side wing 20 and being difficult to take out or clean; while improving the aesthetic appearance of the seat and the riding comfort of the rear passengers.

Specifically, the flexible decoration 31 is made of a flexible material such as leather or woven fabric, and can be designed into different structural shapes according to the step shape and the size of the gap formed by the adjustable backrest 12 and the seat side wings 20, and two sides of the flexible decoration 31 are connected to the adjustable backrest 12 and the seat side wings 20 by sewing or gluing.

Specifically, in an alternative embodiment, the resilient latching portion comprises: a locking clamping groove 32a mounted on the flexible decoration 31 and a locking rod 36 matched with the locking clamping groove 32 a; a rotation driving portion 34 attached to the seat side wings 20, and an elastic member 35 located between the seat side wings 20 and the flexible garnish 31. The rotation driving portion 34 drives the lock lever 36 to rotate by a set angle to switch between a locked position and an unlocked position, and the elastic member 35 applies a force to the flexible garnish 31 away from the seat side flap 20. When the adjustable backrest 12 is located at the first position, the flexible decoration 31 is in a locking state under the action of the elastic locking portion, when the adjustable backrest 12 is adjusted from the first position to the second position, the rotary driving portion 34 drives the locking rod 36 to rotate for a set angle so as to enable the locking rod 36 to rotate to an unlocking position, at the moment, the flexible decoration 31 moves to a set position in a direction away from the seat side wing 20 under the action of the elastic force of the elastic member 35, a gap between the seat side wing 20 and the adjustable backrest 12 can be eliminated through setting the extending direction of the flexible decoration 31 and the external dimension of the flexible decoration 31, and smooth transition between the seat side wing 20 and the adjustable backrest 12 is achieved.

Specifically, the rotary driving part 34 adopts a rotary motor or other electrically controlled actuators capable of realizing a rotary function. In order to control the action of the rotation driving part 34, the vehicle seat further comprises a triggering part (not shown in the figure), the triggering part is triggered by a user (namely, a vehicle occupant), and the control unit controls the rotation driving part 34 to be started and drives the locking rod 36 to rotate for a set angle to be in an unlocking position. The trigger part can be a button, a knob or a trigger switch, etc., and can be arranged at any position of the seat, for example, on the side of the seat side wing 20; it may also be provided on the vehicle body in the vicinity of the seat. Meanwhile, after the triggering portion is triggered, the control unit may also simultaneously control the electric adjustable backrest 12 to perform position switching, for example, when the triggering portion controls the adjustable backrest 12 to move from the first position to the second position, the rotation driving portion 34 is triggered to start at the same time, so that the locking rod 36 is in the unlocking position, and the flexible decoration 31 moves to the setting position in the direction away from the seat side wing 20 under the elastic force of the elastic member 35, so as to realize smooth transition between the seat side wing 20 and the adjustable backrest 12.

In order to realize the automatic switching of the lock lever 36 from the unlock position to the lock position, the vehicle seat further includes a pressure sensor (not shown in the drawings) for detecting a trigger force applied to the flexible garnish 31, the trigger force being a trigger force applied by a user to trigger the flexible garnish 31 to move inward, i.e., toward the seat side wings 20. Normally, when the flexible decoration 31 is in the extended position, the locking rod 36 is unlocked, and when the flexible decoration 31 is required to be in the contracted position, after the user moves to the set position by triggering the flexible decoration 31 to the inside, the locking rod 36 is inserted into the locking slot 32a, at this time, the triggering force reaches the first set value, and the control unit controls the rotary driving part 34 to operate, so that the locking rod 36 rotates by the set angle to enable the locking rod 36 to be matched with the locking slot 32a to be in the locking position. The specific location of the pressure sensor is not unique, and the elastic member 35 can directly transmit the trigger force applied to the flexible decoration 31, so that the pressure sensor can be disposed at one side end of the elastic member 35.

Specifically, in one embodiment, the seat side wings 20 have mounting cavities 20a with openings, and the elastic locking portions are partially disposed in the mounting cavities 20 a. More specifically, the rotation driving portion 34 is located in the mounting cavity 20a, and the rotation driving portion 34 is connected to the seat side wing 20 through a connecting plate 39. The rotation driving portion 34 is mounted on a connecting plate 39, and the connecting plate 39 is detachably connected to the surface of the seat side wing 20 having the mounting cavity 20 a.

Specifically, a locking box 32 is arranged on the flexible decoration 31, an accommodating cavity is formed between the locking box 32 and the back surface of the flexible decoration 31, and the locking clamping groove 32a is formed in the locking box 32. Wherein, locking draw-in groove 32a is the shaping rectangular hole or the waist shape hole on the surface of locking box 32, the tip of lock bar 36 is equipped with rectangle or waist type spring bolt 37, spring bolt 37 with during locking draw-in groove 32a syntropy extends, spring bolt 37 can stretch into in the locking draw-in groove 32a, spring bolt 37 with the extending direction of locking draw-in groove 32a is different, spring bolt 37 joint in the locking of lock bar 36 is realized to the inboard of locking draw-in groove 32a. The locking tongue 37 and the locking clamping groove 32a can be controlled to extend in the same direction by controlling the rotary driving part 34 to rotate 90 degrees along the first direction, so that the locking rod 36 is unlocked; the rotation driving part 34 is controlled to rotate 90 degrees continuously along the first direction or rotate 90 degrees along the reverse direction of the first direction, so that the lock tongue 37 is locked and connected to the lock groove 32a, and the lock of the lock rod 36 is realized.

The inner side of the locking box 32 is further provided with a limiting baffle 38 for limiting the position of the locking tongue 37, and the limiting baffle 38 spans the locking clamping groove 32a and has a set gap with the inner side surface of the locking box 32. When the flexible decorating part 31 is required to move to the contraction position, the lock tongue 37 extends into the lock groove 32a by pushing the flexible decorating part 31, and the limit baffle 38 limits the maximum position of the lock tongue 37 extending.

Specifically, the elastic element 35 is a compression spring, and is installed between the locking rod 36 and the locking box 32, wherein the locking rod 36 is provided with a first step 36a and a second step 36b that are axially spaced, the first step 36a and the second step 36b are transited through a first cylindrical surface 36c, and one end of the compression spring 35 is sleeved on the first cylindrical surface 36c and abuts against the first step 36 a. The outer surface of the locking box 32 is provided with a circular spring seat 32b, and the other end of the compression spring 35 is mounted on the circular spring seat 32 b. The pressure sensor is mounted on the first step 36a, and the compression spring 35 abuts against a trigger surface of the pressure sensor.

The operation principle of the adjustable trim structure 30 of the vehicle seat during seat adjustment is as follows:

when the angle of the adjustable backrest 12 needs to be adjusted to the second position, the triggering part is pressed, and the output end of the rotary driving part 34 drives the locking rod 36 and the rectangular locking tongue 37 to rotate 90 degrees along the first direction along the axis of the locking rod 36. At this time, the rectangular latch tongue 37 and the rectangular latch groove 32a extend in the same direction, and the rectangular latch groove 32a is unlocked from the rectangular latch tongue 37 due to the elastic force of the compression spring 35. The compression spring 35 pushes the lock box 32 to drive the flexible decoration 31 to move, and when the lock box is pressed against the matching surface of the adjustable backrest 12, the movement is stopped, so that the step difference and the gap between the adjustable backrest 12 and the seat side wing 20 are eliminated. Because two sets of same support rod structures with compression springs and locking structures are arranged up and down, the flexible decorating part 31 is stably and tightly attached to the adjustable backrest 12 and the seat side wings 20.

When the adjustable backrest 12 needs to be adjusted to the first position, the flexible decoration 31 is pressed with force, and the flexible decoration 31 pushes the locking box 32 to gradually compress the compression spring 35 reversely. When the flexible decoration 31 is pushed to the bottom, the rectangular latch tongue 37 on the lock lever 36 passes through the rectangular lock notch 32a and enters the lock case 32, and is not locked. As the compression spring 35 continues to be compressed, when the elastic force value of the compression spring 35 monitored by the pressure sensor disposed at the first step 36a of the lock lever 36 is greater than or equal to a set value, the control unit controls the rotation driving part 34 to operate, which drives the lock lever 36 and the rectangular latch 37 to continue to rotate 90 ° in the first direction or rotate 90 ° in the opposite direction to the first direction along the axis of the lock lever 36. When the hands are released, the flexible trim element 31 is locked and the adjustable backrest 12 is adjusted to complete the transition of the adjustable trim structure 30 to the first position of the adjustable backrest 12.

The present application also provides a specific embodiment of a vehicle, which includes the above vehicle seat, and is not described herein again.
