Technical Field

[0001] The invention relates to the field of automobile seat side armrests, in particular to an automobile seat side armrest adjuster assembly. Background Art

[0002] Car seats can be divided into split seats and long seats according to their shape; they can be divided into fixed, detachable and adjustable types according to their functions; they can be divided into single, double and multi-person chairs according to the number of passengers. According to the performance of the seats, they have developed from the earliest fixed seats to multi-functional power-adjustable seats, including air-cushion seats, electric seats, stereo seats, mental recovery seats, and electronically adjustable seats. According to the materials, they can be divided into leather seats and velvet seats, etc. Car seats can be roughly divided into the following types according to their parts: front seats: headrests, backrests, seat cushions, armrests; rear seats: headrests, backrests, seat cushions, side wings, armrests. The side armrests of car seats are used to support people's arms when riding.

[0003] When adjusting the existing side armrests of automobile seats, the side armrests can only be completely adjusted to a horizontal or vertical state, and the angles cannot be adjusted according to people's habits during use, so that people's arm placement positions are uncomfortable. Summary of the invention

[0006] By adopting the above technical solution, the problem of inconvenient angle adjustment of the existing car seat side armrests is solved. When adjusting the angle, the armrest angle can be adjusted by rotating the ring assembly, the auxiliary ratchet assembly, the blocking assembly and the hook plate, and it is limited by the ratchet principle to meet the need for arm support.

[0007] The present invention is further configured such that a first mounting hole, a first insertion hole and a limiting hole are provided inside the shell, a third mounting hole is provided inside the side cover, second rivets are provided inside the first mounting hole and the third mounting hole, and a fixing ring is fixed in the middle of the second rivet.

[0008] By adopting the above technical solution, the second rivet is installed in the first mounting hole and the fourth mounting hole on the outer wall of the shell and the side cover. During installation, the fixing ring on the outer wall of the second rivet fits with the two sides of the shell and the side cover to avoid problems of non-parallelism or insufficient strength during installation. The strength is high and the stability in use is good.

[0009] The present invention is further configured such that a second mounting hole is opened on one side of the shell, a fourth mounting hole is opened inside the side cover, and bolts are arranged inside the fourth mounting hole and the second mounting hole, and the shell and the side cover are fixedly connected by the bolts.

[0010] By adopting the above technical solution, the bolts can fix the housing and the side cover together.

[0011] The present invention is further configured such that a plurality of groups of raised blocks are fixed on the outer wall of the limit member, and grooves are provided inside the raised blocks, an inner groove is provided on one side of the limit member, a protruding block is fixed inside the limit member, and a card slot is fixed on one side of the limit member.

[0012] By adopting the above technical solution, the inner groove on one side of the limit member serves to install the first spring and position the center rod. The inner groove of the limit member is for installing the first spring so that it is positioned inside to prevent movement. The raised block and boss on the outer wall of the limit member are interference fit to ensure concentricity and prevent movement in the limit hole and positioning groove inside the shell. The card groove and the ring on the outer wall of the limit member are used for limiting positioning, so that the concentricity of the axis is more precise and will not affect the rotation of the overall mechanism, thereby achieving lightweight and firmness and increasing service life.

[0013] The present invention is further configured such that a plurality of groups of protruding blocks are fixed to the outer wall of the bottom cover, a plurality of groups of arc blocks are fixed to one side of the bottom cover, an inner hole is opened in the middle of the bottom cover, and a C-shaped semicircular groove is opened on one side of the bottom cover.

[0014] By adopting the above technical solution, the bottom arc block and the protruding block cooperate with the side cover to ensure concentricity and prevent movement in the positioning hole. The C-shaped semicircular groove of the bottom cover and the outer circle of the ring are limited and positioned to make the axial concentricity more precise and will not affect the rotation of the overall mechanism. The inner hole of the bottom cover has a small amount of damping force to solve the risk of insufficient torque. The bottom cover adopts pom highly wear-resistant material, which greatly improves the service life and stability.

[0015] The present invention is further configured such that the engaging member comprises a collar movably mounted on one side of the limiting member, a plum blossom groove is provided inside the collar, and a protrusion is fixed on the outer wall of the collar.

[0016] By adopting the above technical solution, the engaging part and the ring cooperate with the groove on the outer wall of the limiting part to perform positioning and prevent movement, thereby improving concentricity and precise positioning. The protrusion on the outer wall of the ring cooperates with the positioning groove inside the mounting ring to perform limited positioning, so that the mounting ring is driven to rotate as the center rod rotates.

[0017] The present invention is further configured such that a first stopper and a second stopper are fixed to one side of the baffle plate, and a movable hole is opened on one side of the baffle plate.

[0018] By adopting the above technical scheme, the main function of the baffle is to make the second spring able to be unlocked or locked very conveniently. The position of the baffle cooperates with the second spring to act as a preload. The upper boss on one side of the secondary ratchet and the second spring also act as a preload. When both sides of the second spring are supported, the preload will apply force to both sides, so that the toothed ring on the outside of the mounting ring cooperates with the tooth shape of the secondary ratchet to achieve angle adjustment. The position of the baffle is fastened to the shell by the first rivet to make it firm and stable. The first block and the second block on one side of the baffle are engaged with the end of the second spring to prevent the second spring from moving when in the unlocked state and to prevent the second spring from falling off.

[0019] The present invention is further configured such that a shell hole is provided at the bottom of the shell, and a first rivet is provided inside the shell hole.

[0020] By adopting the above technical solution, the baffle can be conveniently fixed inside the shell through the first rivet to prevent it from shaking.

[0021] The present invention is further configured such that washers are sleeved on both ends of the second rivet, and the washers are located at both ends of the fixing ring.

[0022] By adopting the above technical solution, the washers located at both ends of the fixing ring play a role in reducing the gap between the housing and the side cover, and protecting the friction between metal and metal, thereby improving the service life and wear resistance, which complies with mechanical principles.

[0023] In summary, the present invention mainly has the following beneficial effects:

[0024] The present invention solves the problem of inconvenient angle adjustment of the existing side armrests of automobile seats by providing a shell, a side cover, a limiter, a center rod assembly, a first spring and a bottom cover. When adjusting the angle, the armrest angle can be adjusted by rotating the ring assembly, the auxiliary ratchet assembly, the blocking assembly and the hook plate, and it is limited by the ratchet principle, which can meet the need for arm support.
