Description

Technical Field

[0001] This invention relates to the field of automotive safety equipment technology, and more specifically, to a highly stable seat belt height adjustment device. Background Technology

[0002] Car seatbelt height adjusters are typically installed on the B-pillar of a vehicle and are used to adjust the height of the seatbelt, specifically the height of the seatbelt's positioning ring relative to the vehicle body, to accommodate occupants of different heights. To adjust the height, the adjuster is unlocked, and then the seatbelt height is adjusted. However, unlocking existing height adjusters requires considerable hand strength. The most common method involves pressing the unlock buttons on both sides with two fingers, and then moving the adjuster. Because this type of adjuster requires forceful pressing with two fingers and cannot utilize body strength, unlocking it is quite difficult. This makes it challenging for women with insufficient strength or elderly individuals to easily adjust the seatbelt height.

[0003] For example, patent CN201510697988.6 discloses a dual-sided button-type seat belt height adjuster, including a mounting bracket, a sliding unit, a locking pin located within the sliding unit, a return spring, and buttons. The slider support includes a top plate and a pair of side plates extending downwards from both sides of the top plate. The bracket slide rail abuts against the inner surface of the top plate, and the pair of side plates are clamped to the outer surfaces of the pair of side plates. The upper end of the locking pin is engaged with a locking pin fixing member, which has lifting shoulders on both sides. The buttons include a pair of side-press buttons, with a button spring between them. Each side-press button has an inclined surface, and the lifting shoulders rest on these inclined surfaces. The slider and slider support hold the bracket slide rail from both above and below. When adjusting the height of this height adjuster, you need to press and hold the side pressure buttons on both sides to unlock the slider before moving the slider device to achieve the purpose of adjusting the height. The operation is relatively laborious and requires a certain amount of strength in the fingers, making it difficult to easily adjust the height of the seat belt. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a highly stable seat belt height adjustment device.

[0005] The technical solution adopted in this invention is:

[0006] A high-stability seat belt height adjustment device includes: a track section, a movable adjustment section, and a locking control section; the track section is used to connect to a vehicle, and the movable adjustment section for adjusting the seat belt height is slidably connected to the side of the track section away from the vehicle; the movable adjustment section is connected to a locking control section for controlling the movable adjustment section and the track section to lock in relative positions; the locking control section is provided with an interface for threading the seat belt.

[0007] Furthermore, the track section includes: a back plate for connecting the vehicle, a side plate fixed on each of the left and right sides of the back plate, two longitudinally arranged guide ribs fixed on the opposite surfaces of the two side plates, and a guide slide for the movable adjustment section to slide between the two guide ribs; locking holes for connecting the movable adjustment section are provided on the opposite surfaces of the two guide ribs.

[0008] Furthermore, the top and bottom of the back panel and the two side panels can be detachably connected to crossbeams.

[0009] Furthermore, the movable adjustment part includes: a sliding adjustment box, two sliding guide blocks on both sides of the sliding adjustment box are slidably disposed in two guide slides; the two sides of the sliding adjustment box are slidably disposed on the inner sides of two guide vertical ribs; and an opening is provided on the side of the sliding adjustment box near the back plate.

[0010] Furthermore, the locking control unit includes: a through sleeve installed in the central hole of the sliding adjustment box; one end of the through sleeve inserted into the sliding adjustment box is fixedly connected to a control gear; the other end of the through sleeve away from the sliding adjustment box is fixedly connected to a control rotating block; the upper and lower sides of the control gear respectively mesh with a control rack; the two control racks are connected to two sliding control frames; the two sliding control frames are slidably installed in the upper and lower transverse sliding sleeves on the inner wall of the sliding adjustment box; the locking shafts on the two sliding control frames are respectively slidably installed on the left and right sides of the sliding adjustment box; the two locking shafts are inserted into locking holes at different heights on two guide vertical ridges.

[0011] Furthermore, the slide control frame includes: a transverse slide body connected to the control rack and slidably disposed within the transverse slide sleeve; one end of the transverse slide body is fixedly connected to a stop plate for locking onto one side of the control gear; the other end of the transverse slide body is vertically fixedly connected to a support body for mounting the locking shaft; a triangular plate is fixedly connected between the support body and the side wall of the transverse slide body; the stop plate is connected to an assembly plate connected to the side of the sliding adjustment box via a stop spring.

[0012] Furthermore, the guide post fixed to the assembly plate passes through the inside of the stop spring, and the end of the guide post away from the assembly plate slides in the transverse guide hole of the stop plate; a limiting piece is screwed onto the guide post, and the limiting piece abuts against the side of the stop plate away from the stop spring.

[0013] Furthermore, the locking control unit also includes: a control shaft passing through the sleeve, two shaft bosses fixed to the shaft body inserted into the sliding adjustment box, and an axial groove for engaging the two shaft bosses on the inner side of the sleeve; a first retaining ring fixed to the control shaft and a second retaining ring rotating on the sleeve are connected by a tension spring to ensure a gap between the shaft bosses and the sleeve in the normal state; an end seat fixed to the end of the control shaft away from the sliding adjustment box is connected to a mounting bracket for mounting the seat belt via a hinge shaft; when the hinge shaft is laterally perpendicular to the sleeve, the two shaft bosses and the two axial grooves are staggered; when the hinge shaft is longitudinally perpendicular to the sleeve, the two shaft bosses and the two axial grooves engage with each other and can be inserted into the two axial grooves.

[0015] Furthermore, the locking control unit also includes: a ring threaded onto the control shaft located between the sleeve and the end seat; and an anti-loosening spring fixed to the ring engaging with the end seat.

[0016] As can be seen from the above solution, the beneficial effects of the present invention are as follows:

[0017] In this invention, a high-stability seatbelt height adjustment device allows for the unlocking and control of the movable adjustment section and the track section by pulling and rotating the locking control section outwards. Operation can utilize the strength of the entire hand and arm, eliminating the problem of ineffective unlocking due to insufficient finger strength.

Detailed Implementation

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, which will be presented below with reference to the accompanying drawings, it is important to understand that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] Example 1

[0034] Please see Figures 1-10 The present invention provides a high-stability seat belt height adjustment device, comprising: a track section 100, a movable adjustment section 200, and a locking control section 300; the track section 100 is used to connect to a vehicle, and the movable adjustment section 200 for adjusting the seat belt height is slidably connected to the side of the track section 100 away from the vehicle; the locking control section 300 is connected to the movable adjustment section 200 for controlling the movable adjustment section 200 and the track section 100 to lock in relative positions; the locking control section 300 is provided with an interface for threading the seat belt.

[0035] The working principle and technical effects of the above technical solution are as follows:

[0036] In a high-stability seat belt height adjustment device of the present invention, a locking control unit 300 is connected to the movable adjustment part 200 for controlling the relative position locking of the movable adjustment part 200 and the track part 100. When the locking control unit 300 is in contact with the track part 100, the relative locking limit of the movable adjustment part 200 and the track part 100 can be realized. When the locking control unit 300 is separated from the track part 100, the movable adjustment part 200 can be controlled to slide up and down on the track part 100 to meet the usage needs of different users. The present invention improves the adjustment method of the existing seat belt height adjuster, which requires pressing both sides when adjusting. The side-press button method is difficult for people with weak fingers, making it somewhat challenging to operate. The unlocking of this invention is achieved by pulling and rotating the locking control unit 300 outward. Users can utilize the strength of their entire palm and arm, which is significantly greater than the strength of their fingers, making the unlocking process easier. Even children, the elderly, or people with weak hand strength can easily complete the unlocking operation, lowering the operational threshold. The entire adjustment process is relatively simple. Users only need to pull and rotate the locking control unit to slide the movable adjustment unit 200 on the track unit 100, thereby adjusting the seat belt height. This invention fully considers the needs of users with different strength levels. Whether it is a strong adult or a weak child or elderly person, they can easily adjust the height of the seat belt, meeting the needs of a wider range of users and improving user satisfaction. The locking control unit 300 is equipped with a pass-through interface for the seat belt. This design makes it convenient for drivers and passengers to pass the seat belt through and adjust it. The unlocking control function and the seat belt pass-through function are integrated into the locking control unit 300, making the structure of the entire device more compact, reducing unnecessary parts and complex connection methods, which not only reduces the production cost of the product, but also improves the reliability and stability of the product.

[0037] Example 2

[0038] Please see Figures 1-10The track section 100 includes: a back plate 101 for connecting the vehicle; a side plate 102 is fixed to each of the left and right sides of the back plate 101; two longitudinally arranged guide ribs 103 are fixed to the opposite surfaces of the two side plates 102; a guide slide is formed between the two guide ribs 103 for sliding engagement of the movable adjustment section 200; a locking hole 104 for connecting the movable adjustment section 200 is provided on the opposite surfaces of the two guide ribs 103. A cross baffle 105 can be detachably connected to the top and bottom of the back plate 101 and the two side plates 102. The movable adjustment section 200 includes: a sliding adjustment box 201; two sliding guide blocks 202 on both sides of the sliding adjustment box 201 are slidably engaged in the two guide slides; the sides of the sliding adjustment box 201 are slidably engaged on the inner sides of the two guide ribs 103; an opening is provided on the side of the sliding adjustment box 201 near the back plate 101.

[0039] The working principle and technical effects of the above technical solution are as follows:

[0040] In a high-stability seatbelt height adjustment device of the present invention, the track section 100 is the basic support structure of the present invention, used to connect with the vehicle and ensure that the entire adjustment device can be stably installed on the vehicle; two side plates 102 are fixed to the left and right sides of the back plate 101, and two guide vertical ribs 103 on each side plate 102 form a guide slide. The sliding adjustment box 201 of the movable adjustment section 200 slides with the guide slide of the track section 100 through the sliding guide blocks 202 on both sides, so that the sliding adjustment box 201 can slide longitudinally on the track section 100 along the guide slide, providing a clear path and constraint. The two sides of the sliding adjustment box 201 also slide with the inner sides of the two guide vertical ribs 103, further enhancing the stability and accuracy of the sliding; the locking hole 104 on the guide vertical rib 103 is used to cooperate with the movable adjustment section 200 to realize the positioning and locking of the movable adjustment section 200 on the track section 100. The crossbar 105 is detachably connected to the top and bottom of the back panel 101 and the two side panels 102, serving to enclose the track and protect the internal structure. It also helps prevent dust and other debris from entering the track and affecting the sliding of the adjustable section 200. When adjusting the seatbelt height, the locking control 300 is operated to disengage it from the locking hole 104. At this point, the adjustable section 200 can be slid to the appropriate position on the track 100. Then, the locking control 300 is operated to lock the adjustable section 200 in that position, thus completing the seatbelt height adjustment.

[0041] Example 3

[0042] Please see Figures 1-10The locking control unit 300 includes: a through sleeve 301 disposed in the central hole of the sliding adjustment box 201; one end of the through sleeve 301 inserted into the sliding adjustment box 201 is fixedly connected to a control gear 302; the other end of the through sleeve 301 away from the sliding adjustment box 201 is fixedly connected to a control rotating block 303; the upper and lower sides of the control gear 302 respectively mesh with a control rack 304; the two control racks 304 are connected to two sliding control frames 305; the two sliding control frames 305 are slidably disposed in the upper and lower transverse sliding sleeves on the inner wall of the sliding adjustment box 201; the locking shafts 306 on the two sliding control frames 305 are respectively slidably disposed on the left and right sides of the sliding adjustment box 201; the two locking shafts 306 are inserted into locking holes 104 at different heights of the two guide vertical ridges 103. The sliding control frame 305 includes: a transverse slide body 307 connected to the control rack 304 and slidably disposed within a transverse sliding sleeve; one end of the transverse slide body 307 is fixedly connected to a stop plate 308 for engaging with one side of the control gear 302; the other end of the transverse slide body 307 is vertically fixedly connected to a support body 309 for mounting a locking shaft 306; a triangular plate 310 is fixedly connected between the side walls of the support body 309 and the transverse slide body 307; the stop plate 308 is connected to an assembly plate 312 connected to the side of the sliding adjustment box 201 via a stop spring 311. A guide post 313 fixedly disposed on the assembly plate 312 passes through the inner side of the stop spring 311, and the end of the guide post 313 away from the assembly plate 312 is slidably disposed within a transverse guide hole in the stop plate 308.

[0043] The working principle and technical effects of the above technical solution are as follows:

[0044] In a high-stability seat belt height adjustment device of the present invention, the first adjustment method of the locking control unit 300 is as follows: the through sleeve 301 is rotated by the control block 303, thereby realizing the connection or separation of the locking control unit 300 and the locking hole 104. Specifically, in the normal state, the two stop plates 308 are held in a state of being locked on both sides of the control gear 302 by the elastic force of the two stop springs 311. At this time, the two locking shafts 306 are inserted into the locking holes 104 at different heights of the two guide vertical ridges 103. When unlocking, the through sleeve 301 is rotated by the control block 303. The rotation of the through sleeve 301 can drive the control gear 302 to rotate. When the control gear 302 rotates, it meshes and drives the upper and lower control racks 304 to move. The two control racks 304 drive the horizontal sliding bodies 307 of the two sliding frames 305 to slide in the two horizontal sliding sleeves. The outer ends of the two slide control brackets 305 drive the two locking shafts 306 to disengage from the two locking holes 104 via two support bodies 309. The inner ends of the two slide control brackets 305 drive the two stop plates 308 to compress the two stop springs 311. At this time, the sliding adjustment box 201 can be controlled to drive the two sliding guide blocks 202 to slide up and down, thereby realizing the adjustment of the seat belt height. After the adjustment is completed, the control rotating block 303 and the sleeve 301 are released. Under the action of the elastic force of the two stop springs 311, the two stop plates 308 drive the two horizontal slide bodies 307 to reset. The two horizontal slide bodies 307 drive the two locking shafts 306 to re-insert into the two locking holes 104 in the corresponding positions via the two support bodies 309, thereby realizing the stable adjustment of the seat belt. The operation is very convenient. When controlling the rotation of the sleeve 301 by controlling the rotating block 303, it can be controlled by the force of multiple fingers and the palm, which is relatively labor-saving.

[0045] A limiting plate is screwed onto the guide post 313, and the limiting plate abuts against the side of the stop plate 308 away from the stop spring 311. This structure allows control of the minimum distance between the stop plate 308 and the control gear 302, thereby changing the depth to which the two locking shafts 306 are inserted into the two locking holes 104. Note that the two limiting plates must be rotated synchronously for adjustment; otherwise, operation will fail.

[0046] Example 4

[0047] Please see Figures 1-10The locking control unit 300 further includes: a control shaft 314 passing through the sleeve 301; the control shaft 314 is inserted into the shaft body inside the sliding adjustment box 201 and fixed with two shaft bosses 315; the inner side of the sleeve 301 is provided with an axial groove 316 for cooperating with the two shaft bosses 315; a first retaining ring 317 fixed on the control shaft 314 and a second retaining ring 318 rotating on the sleeve 301 are connected by a tension spring 319, so that the shaft bosses 315 are in the normal state with the sleeve. There is a gap between 301; the end seat 320 of the control shaft 314, which is fixed to the end away from the sliding adjustment box 201, is connected to the sleeve bracket 322 for putting on the safety belt through the hinge shaft 321; when the hinge shaft 321 is laterally perpendicular to the sleeve tube 301, the two shaft bosses 315 and the two axial grooves 316 are staggered; when the hinge shaft 321 is longitudinally perpendicular to the sleeve tube 301, the two shaft bosses 315 and the two axial grooves 316 are relatively engaged and can be inserted into the two axial grooves 316.

[0048] The working principle and technical effects of the above technical solution are as follows:

[0049] In a high-stability seatbelt height adjustment device of the present invention, the above solution provides a second adjustment method for the locking control unit 300, as follows:

[0050] Under normal conditions, because a tensioning spring 319 is provided between the first retaining ring 317 and the second retaining ring 318, there is a gap between the shaft boss 315 and the sleeve 301 under normal conditions. Also, because the seat belt is fitted on the sleeve bracket 322, the lower end of the sleeve bracket 322 is inclined downward. The two shaft bosses 315 and the two axial grooves 316 are staggered, and the sleeve 301 will not rotate due to the rotation of the control shaft 314.

[0051] When unlocking is required, the sleeve bracket 322 is pulled outward, causing the control shaft 314 to slide outward within the sleeve tube 301. This compresses the tension spring 319 between the first retaining ring 317 and the second retaining ring 318, simultaneously bringing the shaft boss 315 on the control shaft 314 into contact with the sleeve bracket 322. Then, the sleeve bracket 322 is rotated, controlling the hinge shaft 321 to rotate the control shaft 314. When the shaft boss 315 on the control shaft 314 is aligned with the axial groove 316, the shaft boss 315 is pulled into the axial groove 316. At this point, the control shaft 314 rotates, thereby... The shaft boss 315 and the axial groove 316 work together to drive the through sleeve 301 to rotate, thereby controlling the control gear 302 and thus controlling the unlocking operation. After unlocking, the through sleeve bracket 322 is released, and the first retaining ring 317 and the second retaining ring 318 move away from each other under the elastic force of the tension spring 319. At this time, after the shaft boss 315 separates from the axial groove 316, the control of the through sleeve 301 is released. The control gear 302 and the two control racks 304 on the through sleeve 301 are reset under the elastic force of the two stop springs 311, and the two locking shafts 306 are re-inserted into the two locking holes 104.

[0052] Furthermore, since a tension spring 319 is provided between the first retaining ring 317 and the second retaining ring 318, there is a gap between the shaft boss 315 and the sleeve 301 under normal conditions. During vehicle operation, the seat belt also has a certain amount of room to move. When bumps or sudden braking occur, and the user exerts pressure on the seat belt, the seat belt can drive the sleeve frame 322 and the control shaft 314 to move. The control shaft 314 slides outward inside the sleeve 301 and compresses the tension spring 319. The tension spring 319 plays a buffering and energy-absorbing role, reducing the probability of the seat belt causing injury to the user and improving the comfort of using the seat belt.

[0053] Example 5

[0054] Please see Figures 1-10 A longitudinally arranged bar electromagnet 106 is fixedly connected to the back plate 101. The bar electromagnet 106 is electrically connected to the vehicle power supply. The bar electromagnet 106 and the metal block 323 fixed to the side of the control shaft 314 near the back plate 101 cooperate with each other. When the vehicle starts and the bar electromagnet 106 is powered on, the bar electromagnet 106 and the metal block 323 are magnetically attracted to each other.

[0055] The working principle and technical effect of the above technical solution are as follows: When the vehicle is started and the power is turned on, the bar electromagnet 106 and the metal block 323 are magnetically attracted to each other, further enhancing the stability of the relative position between the control shaft 314 and the back plate 101. When the magnetic attraction force is large, the bar electromagnet 106 can only separate from the metal block 323 when there is a large amplitude of bumps or sudden braking, preventing the seat belt from moving too much and affecting the protective effect. In addition, when the vehicle is not started, the bar electromagnet 106 is not magnetic. At this time, the control shaft 314 is more effortless to control. The purpose of this structure is to make it difficult for the driver to adjust the height of the seat belt while driving, so as to prevent it from affecting driving safety and to allow for safe adjustment before the vehicle is started, ensuring safe use.

[0056] The locking control unit 300 also includes: a ring 324 threadedly connected to the control shaft 314 located between the sleeve 301 and the end seat 320; and an anti-loosening spring 325 fixed on the ring 324 engaging with the end seat 320.

[0057] The working principle and technical effects of the above technical solution are as follows:

[0058] In a high-stability seat belt height adjustment device of the present invention, the structure can limit the relative position of the control shaft 314 and the sleeve 301 to a certain extent. When the rotating ring 324 increases the distance between it and the end seat 320, the length of the control shaft 314 inserted into the sleeve 301 and the sliding adjustment box 201 becomes shorter, the distance between the first retaining ring 317 and the second retaining ring 318 becomes smaller, and the tension spring 319 is initially compressed. During bumps or sudden braking, the buffering distance becomes smaller, meeting the buffering requirements under different road conditions.

[0059] Two opposing arc-shaped damping strips 326 are fixed to the end face of the sleeve 301 near the back plate 101. The connection points between the two arc-shaped damping strips 326 and the axial grooves 316 are rounded. The arc-shaped damping strips 326 not only reduce the noise when the two shaft bosses 315 contact the sleeve 301, but also reduce wear during use. Furthermore, the rounded corners at the connection points make it easier for the two shaft bosses 315 to enter the two axial grooves 316, reducing the probability of jamming.
