Description

Technical Field

[0001] The invention relates to the technical field of automobile technology, and in particular to a recliner assembly for automobile seats. Background Art

[0002] A recliner is a device installed on a car seat to adjust the seat back angle. The device is generally composed of a backrest connecting plate, a seat seat connecting plate, a core component, a hand wheel or an adjustment handle, a return spring, etc. (In some low-cost seats, the backrest connecting plate and the seat seat connecting plate are generally integrated into the backrest frame and the seat frame). According to the continuity of the angle adjustment, it can be divided into a step-by-step adjustment recliner and a stepless adjustment recliner.

[0003] At present, there is a Chinese patent with publication number CN 206186836 U on the market that discloses a recliner assembly for a car seat. Although the recliner can adjust the seat angle, it is found in practice that when people directly apply force to the backrest, the force is transmitted to the tilt arm through the backrest, and causes a relative rotation trend between the tooth plate and the clamping plate. This trend can drive the clamping plate to rotate spontaneously in the direction of separation from the tooth plate, and easily cause the limiting effect of the clamping plate on the tooth plate to disappear. At this time, the tilt arm is not limited by the clamping plate, but can rotate spontaneously, and the angle stability is poor. Summary of the invention

[0004] The object of the present invention is to provide a recliner assembly for a car seat, aiming to solve the problem of poor angle stability.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A recliner assembly for a car seat, comprising:

[0006] A first fixed member and two first movable members which are oppositely arranged and hinged to the first fixed member, wherein the first fixed member is located between the two first movable members, a first locking groove is provided on the first fixed member, a first terminating portion is provided on the first movable member, a first interfering portion is provided on the side of the first fixed member, and the first terminating portion can be separated from or interfering with the first interfering portion by rotating the first movable member;

[0007] A driving rod passing through the two first movable members and being rotationally connected to the two first movable members, wherein a shifting body is provided on the driving rod;

[0008] A transmission body connected to the driving rod;

[0009] A first locking member, the first locking member is rotatably connected to the first movable member, the first locking member includes a first locking portion matched with the first locking groove and a movable groove for matching with the transmission body, the transmission body can drive the first locking portion to be located in the first locking groove or to escape from the first locking groove through the inner wall of the movable groove, when the first locking portion is located in the first locking groove, the first terminating portion and the first contact portion are in contact with each other.

[0010] The present invention is further configured as follows: a first reset body is provided between the two first movable members, a first reset member is provided between the first reset body and the transmission body, and the transmission body portion connected to the first reset member and the first locking member are located on both sides of the driving rod.

[0011] The present invention is further configured as follows: the inner wall of the first locking groove includes a first locking inner wall and a second locking inner wall whose length is greater than that of the first locking inner wall, the first locking inner wall and the second locking inner wall form a √ shape, and the maximum distance between the first interference portion and the second locking inner wall is less than the maximum distance between the first interference portion and the first locking inner wall.

[0012] The present invention is further configured as follows: a longitudinal section of the first locking inner wall is in a concave arc shape, and an outer wall on one side of the first locking portion is movably matched with the shape of the first locking inner wall.

[0013] The present invention is further configured as follows: an anti-slip portion is provided on the first locking member located on the side of the first locking groove, the anti-slip portion is located on the side of the transmission body, and the movable groove is located between the anti-slip portion and the first locking inner wall.

[0014] The present invention is further configured as follows: the toggle body is connected to the end of the driving rod, and one of the first movable members is located between the toggle body and another of the first movable members.

[0015] The present invention is further configured to include:

[0016] a second fixing member and a second movable member hinged to the second fixing member, wherein the second fixing member is provided with a second locking groove, and the second movable member is hingedly provided with a second locking member, wherein the second locking member includes a second locking portion matched with the second locking groove;

[0017] a second reset body, the second reset body being fixedly connected to the second movable member;

[0018] A second restoring member which is continuously in an extended state, wherein two ends of the second restoring member are respectively connected to the second restoring body and the second locking member;

[0019] A second interference portion is provided on the second fixed member, and a second end portion is provided on the second movable member. Rotating the second movable member can cause the second interference portion to interfere with or separate from the second end portion. When the second interference portion interferes with the second end portion, the second locking portion is located in the second locking groove, and the elongation of the second reset member is in a minimum state.

[0020] The present invention is further configured as follows: a locking rod is provided on the second locking member, a driving groove for the locking rod to pass through is opened on the second movable member, a driving cable is provided on the locking rod, and the driving cable and the second locking member are located on both sides of the second movable member.

[0021] The present invention is further configured as follows: the driving groove is in an arc shape, and the shape of the driving groove matches the movable track of the locking rod.

[0022] The present invention is further configured as follows: a connecting piece is arranged between the driving cable and the locking rod, one end of the connecting piece is hinged to the locking rod, and the other end is connected to the driving cable, a limiting body is arranged on the second movable piece, an Ω-shaped limiting groove is provided on the limiting body, one end of the limiting groove passes through one side of the limiting body, and the other end is located in the middle of the limiting body, a first driving part and a second driving part with a diameter larger than the first driving part are arranged in sequence on the driving cable, the first driving part is cylindrical, and the outer wall of the first driving part is slidably matched with the shape of a part of the inner wall of the limiting groove.

[0023] The beneficial effect of the present invention is that when in use, the first fixing member is fixedly connected to the cushion frame of the automobile seat, and the first movable member is fixedly connected to the frame of the seat back. When the backrest is in use, the first terminating portion abuts against the first abutting portion, and the first locking portion on the first locking member is located in the first locking groove. Therefore, when the user applies a force to the backrest in the direction behind the backrest, the first abutting portion limits the first terminating portion, so the first movable member cannot rotate relative to the first fixing member, and the backrest cannot rotate relative to the cushion, that is, within the maximum bearing force range that the adjuster can withstand, even if a large force is applied to the backrest, the backrest will not rotate, and the stability is high.

[0024] At the same time, when the backrest has a force to rotate toward the seat cushion, the inner wall of the first locking groove limits the first locking part, so the first locking part cannot rotate, and the first movable part also cannot rotate. Therefore, at this time, the backrest can better maintain its position stability in both the front and rear directions.

[0025] When the backrest needs to be lowered, it is only necessary to drive the driving rod to rotate through the toggle body, and the driving rod drives the transmission body to rotate, and the transmission body then drives the first locking member to rotate through the inner wall of the movable groove until the first locking portion disengages from the first locking groove. At this time, the backrest can be rotated normally toward the seat until the backrest fits onto the seat cushion; after the first movable member is rotated until the first locking portion is located outside the first locking groove, the toggle body can be released. At this time, even if the first locking member contacts the first fixed member, the first fixed member has no structure that hinders the movement of the first locking member, and therefore the first movable member can rotate normally.

[0026] When erecting the fitted backrest again, it is only necessary to directly rotate the first movable part upwards. During this rotation, the first locking part and the first fixed part slide relative to each other, and in this process, the first fixed part can drive the first locking part to rotate until the first end part and the first interference part form an interference, and the first locking part also enters the first locking groove. This process does not require the operation of the toggle body, which is simple and convenient.

[0027] Among them, since the structure of the present application is mainly composed of the first terminating part and the first resisting part (the backrest is mainly subjected to the force acting toward the rear of the seat), the first terminating part and the first movable part can be integrally formed in actual production, and the first resisting part and the first fixing part can be integrally formed or the first resisting part can pass through the first fixing part, so that both the first terminating part and the first resisting part have greater bearing strength and can well withstand the force applied by the user. Compared with the conventional recliner that uses multiple delicate structures to withstand the force of the backrest, it not only makes the bearing stability better, but also can well extend the service life of the recliner. Similarly, compared with the complex design, the first locking member, the transmission body and other structures also have the advantages of strong bearing capacity, low production cost and long service life.

[0049] The first locking member 9 is rotatably connected to the first movable member 2. The first locking member 9 includes a first locking portion 10 matched with the first locking groove 3 and a movable groove 11 for matching with the transmission body 8. The transmission body 8 can drive the first locking portion 10 to be located in the first locking groove 3 or to escape from the first locking groove 3 through the inner wall of the movable groove 11. When the first locking portion 10 is located in the first locking groove 3, the first termination portion 4 and the first interference portion 5 are in interference.

[0050] A first reset body 12 is disposed between the two first movable members 2 , a first reset member 13 is disposed between the first reset body 12 and the transmission body 8 , and the transmission body 8 portion connected to the first reset member 13 and the first locking member 9 are located on both sides of the driving rod 6 .

[0051] The inner wall of the first locking groove 3 includes a first locking inner wall 3a and a second locking inner wall 3b having a length greater than that of the first locking inner wall 3a. The first locking inner wall 3a and the second locking inner wall 3b form a √ shape. The maximum distance between the first abutting portion 5 and the second locking inner wall 3b is less than the maximum distance between the first abutting portion 5 and the first locking inner wall 3a. The longitudinal section of the first locking inner wall 3a is a concave arc shape, and the outer wall of one side of the first locking portion 10 is flexibly matched with the shape of the first locking inner wall 3a.

The toggle body 7 is connected to the end of the driving rod 6, and one first movable member 2 is located between the toggle body 7 and the other first movable member 2.

[0053] The angle adjuster assembly also includes:

[0054] A second fixed member 15 and a second movable member 16 hinged to the second fixed member 15, the second fixed member 15 is provided with a second locking groove 17, wherein the second locking groove 17 includes a third locking inner wall 17a and a fourth locking inner wall 17b whose length is greater than the third locking inner wall 17a, the third locking inner wall 17a and the fourth locking inner wall 17b form a √ shape (similar in shape to the first locking inner wall 3a and the second locking inner wall 3b), the second movable member 16 is hingedly provided with a second locking member 18, the second locking member 18 includes a second locking portion 19 matched with the second locking groove 17;

[0055] A second reset body 20, wherein the second reset body 20 is fixedly connected to the second movable member 16;

[0056] A second restoring member 21 which is continuously in an extended state, wherein two ends of the second restoring member 21 are respectively connected to the second restoring body 20 and the second locking member 18;

[0057] A second interference portion 22 is provided on the second fixed member 15, and a second end portion 23 is provided on the second movable member 16. Rotating the second movable member 16 can cause the second interference portion 22 to interfere with or separate from the second end portion 23. When the second interference portion 22 interferes with the second end portion 23, the second locking portion 19 is located in the second locking groove 17, and the elongation of the second reset member 21 is at a minimum state.

[0058] The second locking member 18 is provided with a locking rod 24, the second movable member 16 is provided with a driving groove 25 for the locking rod 24 to pass through, the locking rod 24 is provided with a driving cable 26, and the driving cable 26 and the second locking member 18 are located on both sides of the second movable member 16. The driving groove 25 is arc-shaped, and the shape of the driving groove 25 matches the moving track of the locking rod 24.

[0059] A connecting piece 27 is arranged between the driving cable 26 and the locking rod 24, one end of the connecting piece 27 is hinged to the locking rod 24, and the other end is connected to the driving cable 26, a limiting body 28 is arranged on the second movable member 16, an Ω-shaped limiting groove 29 is opened on the limiting body 28, one end of the limiting groove 29 passes through one side of the limiting body 28, and the other end is located in the middle of the limiting body 28, a first driving part 30 and a second driving part 31 with a diameter larger than the first driving part 30 are arranged on the driving cable 26 in sequence, the first driving part 30 is cylindrical, and the outer wall of the first driving part 30 is slidably matched with the shape of a part of the inner wall of the limiting groove 29.

[0060] The present invention provides a recliner assembly for a car seat, in which, when in use, the first fixing member 1 is fixedly connected to the cushion frame of the car seat, and the first movable member 2 is fixedly connected to the frame of the seat back. When the backrest is in use, the first end portion 4 abuts against the first abutting portion 5, and the first locking portion 10 on the first locking member 9 is located in the first locking groove 3. Therefore, when the user applies a force to the backrest in the direction behind the backrest, the first abutting portion 5 limits the first end portion 4, so the first movable member 2 cannot rotate relative to the first fixing member 1, and the backrest cannot rotate relative to the cushion, that is, within the maximum bearing force range that the adjuster can withstand, even if a larger force is applied to the backrest, the backrest will not rotate, and the stability is high.

[0061] At the same time, when the backrest has a force to rotate toward the seat cushion, the inner wall of the first locking groove 3 limits the first locking part 10, so the first locking member 9 cannot rotate, and the first movable member 2 also cannot rotate. Therefore, at this time, the backrest can better maintain its position stability in both the front and rear directions.

[0062] When the backrest needs to be lowered, it is only necessary to drive the driving rod 6 to rotate through the toggle body 7, and the driving rod 6 drives the transmission body 8 to rotate, and the transmission body 8 then drives the first locking member 9 to rotate through the inner wall of the movable groove 11 until the first locking portion 10 is disengaged from the first locking groove 3. At this time, the backrest can be rotated normally toward the seat until the backrest fits onto the seat cushion; after rotating the first movable member 2 until the first locking portion 10 is located outside the first locking groove 3, the toggle body 7 can be released. At this time, even if the first locking member 9 contacts the first fixed member 1, the first fixed member 1 has no structure that hinders the movement of the first locking member 9, so the first movable member 2 can rotate normally.

[0063] When erecting the fitted backrest again, it is only necessary to directly rotate the first movable part 2 upwards. During this rotation, the first locking part 9 and the first fixed part 1 slide relative to each other, and in this process, the first fixed part 1 can drive the first locking part 9 to rotate until the first end part 4 and the first contact part 5 form a conflict, and the first locking part 9 also enters the first locking groove 3. This process does not require the operation of the toggle body 7, which is simple and convenient.

[0064] Among them, since the structure of the present application is mainly composed of the first terminating part 4 and the first resisting part 5 (the backrest is mainly subjected to the force acting toward the rear of the seat), the first terminating part 4 and the first movable part 2 can be integrally formed in actual production, and the first resisting part 5 and the first fixing part 1 can be integrally formed or the first resisting part 5 can pass through the first fixing part 1, so that both the first terminating part 4 and the first resisting part 5 have greater bearing strength and can well withstand the force applied by the user. Compared with the conventional recliner that uses multiple delicate structures to withstand the force of the backrest, it not only makes the bearing stability better, but also can well extend the service life of the recliner. Similarly, compared with the complex design, the first locking member 9, the transmission body 8 and other structures also have the advantages of strong bearing capacity, low production cost and long service life.

[0065] When the first locking portion 10 is located in the first locking groove 3, the first reset member 13 (preferably a spring) is in an extended state. At this time, the first reset member 13 allows the transmission body 8 to continue to have a tendency to rotate, and also allows the transmission body 8 to continue to resist against the inner wall of the movable groove 11. Under the resistance of the transmission body 8, the first locking member 9 has a tendency to continue to rotate downward. Under the effect of this tendency, the first locking member 9 can be prevented from spontaneously detaching from the first locking groove 3. Even when the road is bumpy or a vehicle collision occurs, the first locking member 9 can be stably located in the first locking groove 3 and prevent the backrest from spontaneously rotating in the direction of fitting the seat, thereby improving stability.

[0066] When lowering the backrest to fit the seat, the operator rotates the transmission body 8 by means of the shifting body 7. After the rotation of the transmission body 8 drives the first locking member 9 to rotate, the first locking portion 10 disengages from the first locking groove 3. During this process, the length of the first reset member 13 is further extended, and the elastic restoring force is also greater. After the backrest is rotated to a certain extent, the shifting body 7 is released, the first reset member 13 drives the transmission body 8 to rotate, and the transmission body 8 drives the first locking member 9 to rotate. However, at this time, the first locking member 9 and the first locking portion 10 can only contact the first fixing member 1 on the side of the first locking groove 3, and do not affect the normal rotation of the first movable member 2 and the backrest.

[0067] The first locking inner wall 3a and the second locking inner wall 3b form a √ shape, and the first locking inner wall 3a is shorter and has a larger inclination. Therefore, when the backrest is subjected to a non-human rotation force (toward the seat), it is difficult for the first locking portion 10 to slide relative to the first locking inner wall 3a, so the stability of the backrest can be higher. In addition, since the first locking inner wall 3a is a concave arc shape, the first locking portion 10 is a convex arc shape. Therefore, when the backrest is subjected to a non-human rotation force, the first locking inner wall 3a can not only provide a horizontal resistance to the first locking portion 10, but also provide a vertical resistance, so that the first locking inner wall 3a has a better limiting effect on the first locking portion 10;

[0068] Moreover, the arc shape of the first locking inner wall 3a and the arc degree of the outer wall of the first locking portion 10 are matched with the movement trajectory of the first locking portion 10, that is, when the first locking member 9 is driven to rotate by the shifting body 7 and the transmission body 8, the first locking portion 10 rotates in a state of being in contact with the first locking inner wall 3a. Therefore, firstly, the first locking member 9 can rotate normally. Secondly, during the use of the backrest, the first locking portion 10 and the first locking inner wall 3a are linearly fitted. Therefore, not only the interference stability between the two is higher, but also the backrest is subjected to greater force in the direction of the seat.

[0069] The anti-slipping part 14 increases the height of the side wall of the movable groove 11, so when the transmission body 8 drives the first locking member 9 to rotate, it can better prevent the transmission body 8 from separating from the first locking member 9, that is, the anti-slipping part 14 can make the transmission body 8 continue to act on the first locking member 9 stably, and the use stability is high. The toggle body 7 is located outside the two first movable members 2, so it can prevent the toggle body 7 from interacting with other structures of the recliner, thereby improving the structural stability of the recliner.

[0070] In a preferred embodiment, the first fixed member 1 and the first movable member 2 are both used on the middle seat of the rear seat of the car, while the second fixed member 15 and the second movable member 16 are both used as the side members, or are located on the armrest of the middle seat; similarly, when the second fixed member 15 and the second movable member 16 are in use (i.e., when supporting the weight of a human body), the second interference portion 22 and the second termination portion 23 form an interference with each other, and the two can support the force applied by the human body, and in the direction opposite to the supporting direction, the inner wall of the second locking groove 17 limits the second locking member 18, thereby preventing the second movable member 16 from spontaneously rotating toward the direction of the seat.

[0071] When it is necessary to rotate the second movable member 16 toward the seat direction, the second driving member 31 is first used to sequentially drive the first driving member 30, the driving cable 26, the connecting member 27, and the locking rod 24 to move, and at the same time the locking rod 24 drives the second locking member 18 to rotate. During the rotation of the second locking member 18, the second locking member 19 disengages from the second locking groove 17. At this time, the second locking member 18 can rotate without being limited by the second locking groove 17; similarly, when the second locking member 19 is rotated to separate from the second locking groove 17, the second driving member 31 is released, and the second reset member 21 causes the second locking member 19 to contact the outer wall of the second fixing member 15 under the elastic force. When the second movable member 16 is erected to support the human body, it is only necessary to directly rotate the second movable member 16 upwards, and when the second locking portion 19 moves to the position of the second locking groove 17, the second locking portion 19 slides into the second locking groove 17 under the elastic force of the second reset member 21; during the sliding process of the second locking portion 19, the second contact portion 22 and the second end portion 23 form a contact, and after the second locking member 18 completely slides into the second locking groove 17, the outer wall of the second locking member 18 is completely fitted to one side of the second locking groove 17, so the inner wall of the second locking groove 17 is also an inwardly concave arc shape, and the outer side of the second locking portion 19 is an outwardly convex arc shape.

[0072] The driving cable 26 is fixedly connected to the connecting member 27, but the connecting member 27 is hinged to the locking rod 24, so when the driving cable 26 drives the locking rod 24 to move, it is done by rotating between the connecting member 27 and the locking rod 24, which prevents the wear of the driving cable 26 and prolongs its service life. When the locking rod 24 rotates, the inner walls on both sides of it continuously move against the inner walls of the driving groove 25, so the inner walls of the driving groove 25 can also limit the locking rod 24, preventing excessive torque from being generated between the locking rod 24 and the second locking member 18, and protecting the recliner.

[0073] The limiting groove 29 is Ω-shaped, and the first driving part 30 is located on the inner wall of the limiting groove 29 and is slidably connected to the limiting groove 29, wherein the curvature of the inner wall of the limiting groove 29 is greater than 180 degrees, so the inner wall of the limiting groove 29 can limit the first driving part 30 and prevent the first driving part 30 from being dragged out of the limiting groove 29, and the diameter of the second driving part 31 is greater than that of the first driving part 30, so the second driving part 31 can prevent the first driving part 30 from completely escaping from the limiting groove 29.

[0074] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
