Description

Technical Field

[0001] The utility model relates to the field of personnel safety protection of vehicles, in particular to a seat belt restraint system for passengers. Background Art

[0002] The increasing prevalence of rapid transportation has led to increasing attention to passenger safety, especially post-collision protection. A variety of seatbelt restraint systems exist for different applications. Commonly used are three-point seatbelts, which secure the belt to anchor points on the vehicle body and seat, securing the occupant's chest and abdomen. These systems offer a good balance between safety and ease of use, and have gained widespread adoption.

[0003] In addition, there are a variety of other types of occupant seatbelt restraint systems, each with its own advantages and disadvantages, and are only used in limited scenarios. Two-point seatbelts only cross the belt across the abdomen or hips, offering a simple structure and ease of use, but insufficient protection. Four-point seatbelts typically utilize four anchors on the vehicle backrest and seat surface, forming a cross-belt restraint in front of the body. While providing strong protection, they offer limited protection against slippage and sinking. Quick-release buckles are often used across the chest for ease of donning and donning. Five-point seatbelts add a leg belt to the four-point system, providing some protection against slippage and sinking. Six-point seatbelts typically utilize two anchors on the vehicle backrest and four on the seat surface, restraining the occupant's chest, abdomen, and legs. These seatbelt restraint systems all share a common characteristic: they are designed for occupants sitting at shallow angles; they offer limited protection for reclining at large angles. Furthermore, seatbelts with more than four points are generally rigid and cannot be used with retractors, making donning and donning extremely inconvenient, limiting their application.

[0004] As intelligent driving technology matures and becomes more widespread, vehicles are no longer simply transportation tools; they are becoming increasingly integrated into living spaces. Diverse seating layouts, zero-gravity seats, swivel seats, reclining seats, and other seat styles are increasingly being introduced. While meeting diverse consumer needs, these features also pose greater challenges to occupant safety. The increasing prevalence of automated braking systems like AEB and the increasing number of emergency braking situations are placing greater demands on occupant restraint, necessitating new seatbelt restraint systems that are more user-friendly.

[0005] Multiple studies have shown that existing seatbelt restraint systems fail to meet the required protection requirements for occupants in a high-angle rearward recline. Chen Yongxu et al. (Chen Yongxu et al., Analysis of the Hybrid III 50th Dummy's Damage and Restraint System in Zero-G Position Under Collision Conditions, Automobile & New Power, 2023, 12, vol. 6. no. 6, pp. 35-37) suggest that zero-gravity seats equipped with three-point seatbelts should not have a seatback angle greater than 40° while in motion, and that four-point seatbelts offer limited protection.

[0006] Therefore, there is an urgent need for an occupant protection system that can well restrain occupants in a variety of postures, especially in a large-angle lying posture, to meet the user's diverse riding postures, convenient buckling and detaching, and good protection requirements. Summary of the Invention

[0007] The utility model provides an occupant safety belt restraint system that utilizes anchor points on vehicles such as the vehicle body and seats for connection or fixation. It can provide good multi-position occupant protection, is easy to tie and undock, and has a simple structure. The occupants referred to include not only passengers but also the driver and other passengers.

[0008] The occupant safety belt restraint system includes a self-locking retractor, a quick-release buckle, a left restraint belt, a right restraint belt, and a non-slip restraint belt. The left restraint belt, right restraint belt, and non-slip restraint belt can be broadly referred to as restraint belts. The self-locking retractor and restraint belt are connected to anchor points on the vehicle body, seat, or other vehicle components via anchor points. An anchor point may be a structural component or simply a connection to the anchor point without a specific structure; the connection may be fixed or slidable.

[0009] The anchor points connected to the anchor points of this system are located on vehicles such as the vehicle body and seats. Using the anchor points on the seats will provide greater restraint and flexibility. The vehicle anchor points can be additional settings for this system, such as setting up special anchor points at the back or inside of the vehicle back, under or inside the bed board, or on both sides of the seat surface; or using existing interfaces on the vehicle, such as ISOFIX interface, TOP-TETHER interface, LATCH interface, seat belt latch port, etc.; or making appropriate additions and modifications to the above interfaces, such as adjusting the width of the webbing interface on the ISOFIX interface lead-out device to facilitate the sliding or fixing of the restraint belt inside. The preferred anchor point arrangement is: setting an anchor point to fix the self-locking retractor inside the vehicle backrest, leading the restraint belt from the outlet above the shoulder of the backrest, and using the ISOFIX interfaces on the left and right sides of the rear of the vehicle seat surface as anchor points to connect with the restraint belt.

[0010] A self-locking retractor is a commonly used seatbelt retractor. One end of the retractor serves as an anchor point for connection to the vehicle body or seat. The other end is the free end of the retractor's webbing, which can be connected to a three-way connection, which in turn connects to one end of the left or right restraint. Alternatively, the free end of the webbing can be extended directly to form the left or right restraint. The retractor opens with a gentle pull to provide greater freedom of movement, but it self-locks with a quick pull, maintaining rigidity and providing restraint protection in the event of a collision.

[0011] The quick-release lock is located in front of the passenger's chest and abdomen and is made of high-strength materials such as plastic and metal. It includes a main body, an unlocking button, a movable locking plate, and a locking position for the movable locking plate.

[0012] The main body is a quick-release buckle, with left and right restraint strap connection points on the upper part. The left and right restraint strap connection points can be divided into a left-side left and right restraint strap connection point and a right-side left and right restraint strap connection point. The left restraint strap runs through the left-side left and right restraint strap connection point, and the right restraint strap runs through the right-side left and right restraint strap connection point; the restraint straps can slide freely within the left and right restraint strap connection points. Normally, the left-side left and right restraint strap connection points and the right-side left and right restraint strap connection points are two independent connection points, but they can also be combined into one connection point, or they can be drawn out from the main body through webbing, straps or other lead-out mechanisms and then connected to the left and right restraint straps. There is at least one movable locking plate locking position at the lower part of the main body. When there is only one movable locking plate, there is an anti-slip restraint strap connection position on the other side of the main body opposite to the movable locking plate locking position; when there are two movable locking plates, the anti-slip restraint strap connection positions are located on both movable locking plates.

[0013] The unlock button contains a locking and unlocking mechanism. The movable locking piece engages with the locking piece, locking the lock. The user unlocks the unlock button to release the lock, and the movable locking piece automatically pops open or can be removed. The unlock button is located on the body or the movable locking piece and can be one or more, in various forms or combinations, such as buttons, paddles, and buckles.

[0014] The movable locking plate has an anti-slip restraint belt connection position and a latching position. The anti-slip restraint belt connection position is connected to one end of the anti-slip restraint belt, and the latching position is inserted into the movable locking plate locking position on the main body. The anti-slip restraint belt connection position on the movable locking plate or the quick-release lock buckle main body is connected to the two ends of the anti-slip restraint belt. The connection method with the anti-slip restraint belt can be that the anti-slip restraint belt directly penetrates to form a movable connection, or it can be that a ring belt or other structure is inserted into the anti-slip restraint belt connection position to form a fixed connection. The anti-slip restraint belt connection position on the movable locking plate or the quick-release lock buckle main body can also have a length adjustment mechanism to adjust and maintain the length of the anti-slip restraint belt. A more preferred method is to have a one-way adjustment mechanism at the anti-slip restraint belt connection position, which can adjust the anti-slip restraint belt in one direction in the direction of tightening the occupant and maintain the length of the anti-slip restraint belt to tighten the occupant. The latching position of the movable locking plate referred to here does not necessarily refer to a tongue-shaped structure protruding outward. It can also be that the latching position is concave inward, and the locking position of the movable locking plate is a protruding tongue-shaped structure, or other structures that can be locked and unlocked.

[0015] The left restraint belt, right restraint belt and anti-slip restraint belt are used to restrain the body of the occupant, and are collectively referred to as restraint belts. The restraint belt can be connected to the self-locking retractor through a three-way structure, or it can be directly extended from the webbing of the self-locking retractor. When there is only one self-locking retractor, its free end has a three-way structure, and the left restraint belt and the right restraint belt are connected to one side of the three-way structure. When there are two self-locking retractors, the restraint belt is extended from the free end of the webbing of the self-locking retractor. The anti-slip restraint belt provides additional restraint for the user's slippage when taking a large-angle lying position by giving additional restraint to the occupant's hips, waist, buttocks or legs. A more preferred way is to restrain the occupant at the hip bone, taking advantage of the fact that the hip bone has less movement and a stronger structure, to provide good restraint while trying not to affect the occupant's movement.

[0016] The three types of restraint belts, namely the left restraint belt, the right restraint belt and the anti-slip restraint belt, can be three independent belts, or the left restraint belt and the right restraint belt can be a continuous whole, or all three can be a continuous whole.

[0017] In each of the three independent restraint belt systems, one end of the left restraint belt is connected to the self-locking retractor's tee structure or extends from the self-locking retractor. It then passes through the left-side left-right restraint belt connection on the quick-release buckle body and is fixedly connected to the anchor point on the left side of the vehicle seat surface. The left restraint belt can slide within the left-side left-right restraint belt connection. The right side is arranged similarly.

[0018] The left and right restraint straps form a continuous, integrated unit, while the anti-slip restraint strap is a separate system. One end of the left restraint strap is connected to the self-locking retractor's tee structure or extends from the self-locking retractor. It then passes through the left-right restraint strap connection on the quick-release buckle body and connects to the anchor on the left side of the vehicle seat surface. It then crosses over the seat surface to the right side to form the right restraint strap, connecting to the anchor on the right side of the vehicle seat surface. After passing through the right-right restraint strap connection on the quick-release buckle body, it connects to the self-locking retractor. In this system, the portion of the restraint strap extending from the self-locking retractor's tee structure or the left self-locking retractor to the center of the vehicle seat surface is the left restraint strap, and the portion between the center of the vehicle seat surface and the self-locking retractor's tee structure or the right self-locking retractor is the right restraint strap. The restraint strap can slide within the left-right restraint strap connection on the left side, the anchor on the left side of the vehicle seat surface, the right-left restraint strap connection, and the anchor on the left side of the vehicle seat surface. The left end of the anti-slip restraint is connected to the left anti-slip restraint connection point. After passing around the occupant from the rear and bottom, the right end connects to the right anti-slip restraint connection point, forming an independent structure. To further restrain the occupant, a connecting strap is located in the middle of the anti-slip restraint, which connects to the restraint strap across the vehicle seat surface to provide additional restraint.

[0019] In a system where the left restraint belt, right restraint belt, and anti-slip restraint belt are all continuous and integrated, one end of the left restraint belt is connected to the three-way structure of the self-locking retractor or extends from the self-locking retractor, passes through the left-side left-right restraint belt connection point on the quick-release lock body, and connects to the anchor point on the left side of the vehicle seat surface; then passes through the left movable locking plate or the anti-slip restraint belt connection point on the quick-release lock body, and then passes around the occupant from the rear and bottom, and passes through the right movable locking plate or the anti-slip restraint belt connection point on the quick-release lock body; the restraint belt is then connected to the anchor point on the right side of the vehicle seat surface, passes through the right-side left-right restraint belt connection point on the quick-release lock body, and connects to the self-locking retractor. In this system, the portion between the restraint belt extending from the three-way structure of the self-locking retractor or the left self-locking retractor and the anti-slip restraint belt connection on the left is the left restraint belt, the portion between the left anti-slip restraint belt connection and the right anti-slip restraint belt connection is the anti-slip restraint belt, and the portion between the right anti-slip restraint belt connection and the three-way structure of the self-locking retractor or the right self-locking retractor is the right restraint belt. The restraint belt can slide within the left left and right restraint belt connection, the anchor position on the left side of the vehicle seat surface, the anti-slip restraint belt connection on the left movable locking plate or quick-release buckle body, the anti-slip restraint belt connection on the right movable locking plate or quick-release buckle body, the anchor position on the right side of the vehicle seat surface, and the left and right restraint belt connection on the right side.

[0020] After combining the above structures, the following complete system form can be formed.

[0021] The system includes a self-locking retractor, a quick-release lock buckle, a left restraint belt, a right restraint belt and an anti-slip restraint belt; the quick-release lock buckle includes a body, an unlocking button and a movable locking plate; the upper part of the body is provided with left and right restraint belt connecting positions, and the lower part is provided with at least one movable locking plate locking position; after the left and right restraint belts pass through the left and right restraint belt connecting positions, they are connected to the anchor position on the carrier; at least one end of the anti-slip restraint belt is connected to the connecting position of the movable locking plate, and the locking position of the movable locking plate is movably connected to the movable locking plate locking position of the body.

[0022] The system has a self-locking retractor with three anchor points. One end of the self-locking retractor is fixed to the anchor position at the rear of the vehicle as an anchor point, and the other end has a three-way structure, which is connected to one end of the left restraint belt and the right restraint belt respectively through the three-way structure. The left restraint belt and the right restraint belt each have an anchor point connected to the anchor position of the vehicle seat surface.

[0023] Alternatively, the system has two self-locking retractors with a total of four anchor points; one end anchor point of the left self-locking retractor is fixed to the anchor position on the left side of the vehicle backrest, and the other end extends through the left outlet on the upper part of the vehicle backrest to form a left restraint belt, which is connected to the anchor position of the vehicle seat surface through the anchor point; the right side is arranged similarly.

[0024] In the case where the left and right restraint belts are non-continuous independent structures, the left restraint belt connected to the self-locking retractor passes through the left and right restraint belt connection position on the quick-release lock body, and the other end is connected to the fixed anchor point on the left side of the vehicle seat surface as an anchor point, terminating there; the right side is arranged similarly.

[0025] When the left and right restraint belts are a continuous integral restraint belt structure, the structures connecting the integral restraint belt from one end to the other are the self-locking retractor, the left and right restraint belt connection positions on this side of the quick-release lock buckle body, the anchor position on this side of the vehicle seat surface, the anchor position on the other side of the vehicle seat surface, the left and right restraint belt connection positions on the other side of the quick-release lock buckle body, and the self-locking retractor.

[0026] When the left restraint belt, the right restraint belt and the anti-slip restraint belt are all continuous integral restraint belt structures, they include two movable locking plates, and both ends of the anti-slip restraint belt are connected to the anti-slip restraint belt connection positions on the movable locking plates; the structure in which the integral restraint belt is connected in sequence from one end to the other end is a self-locking retractor, the left and right restraint belt connection positions on this side of the quick-release lock buckle body, the anchor position on this side of the vehicle seat surface, the movable locking plate connection position on this side, the movable locking plate connection position on the other side, the anchor position on the other side of the vehicle seat surface, the left and right restraint belt connection positions on the other side of the quick-release lock buckle body, and a self-locking retractor; the restraint belt between the movable locking plate connection position on this side and the movable locking plate connection position on the other side forms an anti-slip restraint belt, which passes around the occupant from the rear and bottom to form a restraint on the occupant's hips.

[0027] Alternatively, the left restraint belt, the right restraint belt and the anti-slip restraint belt are all continuous integral restraint belt structures, including a movable locking plate, and the two ends of the anti-slip restraint belt are respectively connected to the movable locking plate and the anti-slip restraint belt connection position on the quick-release lock buckle body; the structure in which the integral restraint belt is connected in sequence from one end to the other end is a self-locking retractor, the left and right restraint belt connection positions on this side of the quick-release lock buckle body, the anchor position on this side of the vehicle seat surface, the anti-slip restraint belt connection position on this side, the movable locking plate connection position on the other side, the anchor position on the other side of the vehicle seat surface, the left and right restraint belt connection positions on the other side of the quick-release lock buckle body, and a self-locking retractor; the restraint belt between the anti-slip restraint belt connection position on this side and the movable locking plate connection position on the other side forms an anti-slip restraint belt, which passes around the occupant from the rear and bottom to form a restraint on the occupant's hips.

[0028] The features and advantages of this system are:

[0029] First, this system uses a self-locking retractor, which overcomes the disadvantage of conventional four-point or more seat belts that are difficult to relax after tightening the occupants, making the occupants' posture more flexible, independent and relaxed, and improving the occupants' acceptance and usage rate of the seat belt restraint system.

[0030] Second, anti-slip restraints located at the hips and other areas prevent the body from sliding down in high-angle sitting positions or even in a supine position, providing sufficient restraint to enhance safety in collision or AEB situations. In particular, the integrated structure of the left and right restraints and anti-slip restraints ensures that, after the self-locking retractor automatically locks in a collision, any occupant movement in any direction will be tightened by the anti-slip restraints, thereby limiting further slippage.

[0031] Third, the quick-release buckle makes it easy for users to put on and take off. The left and right restraints are directly connected to the quick-release buckle, while the anti-slip restraint uses a movable locking plate. Users can quickly release the hip restraint structure by lifting the quick-release buckle from above their body to release the restraint; the entire operation is convenient and quick.

DETAILED DESCRIPTION

[0040] The following describes an embodiment of the present invention in detail with reference to the accompanying drawings. However, the present invention may be implemented in a variety of different ways as defined and covered by the claims and technical solutions. Directional terms such as front, back, left, right, up, down, etc. in this specification are based on the perspective of the occupant constrained by this embodiment, and different combinations may result in corresponding changes.

[0041] This embodiment adopts the form of an integral restraint belt, that is, the left restraint belt 31, the anti-slip restraint belt 32 and the right restraint belt 33 are a continuous and integrated integral structure.

[0042] In this embodiment, the anchor points for connecting to the vehicle are all located on the seat, specifically including an anchor point located on the left side of the seat back, an anchor point 412 located on the right side of the vehicle back, an anchor point 421 located on the left side of the vehicle seat surface, and an anchor point 422 located on the right side of the vehicle seat surface. In this embodiment, there are two self-locking retractors 1, each mounted on the inside of the vehicle back 41. The anchor point 11 of the right self-locking retractor 1 is fixedly connected to the anchor point 412 located on the right side of the vehicle back.

[0043] The free end of the webbing 12 of the self-locking retractor 1 extends from the right restraint belt outlet 13 above the shoulder of the vehicle backrest 41, forming the right restraint belt 33. The left side has a similar layout. This embodiment includes two movable locking plates: a left movable locking plate 24 and a right movable locking plate 25.

[0044] After the right restraint belt 33 passes through the left and right restraint belt connection position 23 on the right side of the main body 21 of the quick-release lock buckle 2, it passes through the right side anchor position 422 of the vehicle seat surface, moves forward through the non-slip restraint belt connection position 252 on the right movable locking plate, goes around the occupant's hips to the front, passes through the non-slip restraint belt connection position 242 on the left movable locking plate, passes through the left side anchor position 421 of the vehicle seat surface, and then passes through the left and right restraint belt connection position 22 on the left side of the main body 21 of the quick-release lock buckle 2. It enters the vehicle backrest from the left restraint belt outlet 14 above the shoulder of the vehicle backrest 41 and is connected to the webbing 12 of the left self-locking retractor 1.

[0045] The portion of the entire restraint strap between the right restraint strap outlet 13 and the anti-slip restraint strap connection point 252 of the right movable locking plate is the right restraint strap 33. The portion between the anti-slip restraint strap 252 of the right movable locking plate and the anti-slip restraint strap connection point 242 of the left movable locking plate is the anti-slip restraint strap 32. The portion between the anti-slip restraint strap connection point 242 of the left movable locking plate and the left restraint strap outlet 14 is the left restraint strap 31. The restraint strap is slidable at the connections between the right restraint strap outlet 13, the right side left and right restraint strap connection points 23 on the main body 21 of the quick-release buckle 2, the right side anchor point 422 of the vehicle seat surface, the anti-slip restraint strap connection point 252 of the right movable locking plate, the anti-slip restraint strap connection point 242 of the left movable locking plate, the left side anchor point 421 of the vehicle seat surface, the left side left and right restraint strap connection points 22 on the main body 21 of the quick-release buckle 2, and the left restraint strap outlet 14. The sliding of the restraint belts at different connection points causes the lengths of the right restraint belt 33 , the anti-slip restraint belt 32 , and the left restraint belt 31 to change.

[0046] When the movable locking plate is unlocked, the quick-release buckle 2 is pulled upward by the retraction force of the webbing 12 of the self-locking retractor 1, and the restraint belt is now in a relatively short position. In the shortest position, the quick-release buckle 2 can even be stored in the shoulder space between the right restraint belt outlet 13 and the left restraint belt outlet 14, without affecting the riding experience when the occupant is stationary.

[0047] When the vehicle is in motion, the occupant simply pulls the quick-release buckle 2 down from the head to the chest and abdomen, inserting the left and right movable locking plates' latching positions 241 and 251 into the movable locking plate locking positions 26 of the quick-release buckle 2 to lock the restraint belt. To achieve a better restraint effect, the restraint belt can be pulled outward using the one-way adjustment mechanism 201 at the non-slip restraint belt connection point, allowing the non-slip restraint belt 32 to more tightly secure the occupant's hips. Because the hips and pelvis are fixed structures and not in a stress-bearing position, tightening the belt does not cause any additional discomfort.

[0048] In the event of a collision or AEB emergency braking, the restraint belt will restrain the occupants from rushing forward or sliding rapidly.

[0049] When the passenger takes a small-angle sitting position, the upper body is in an upright state. The overall forward movement will quickly pull the left restraint belt 31 and the right restraint belt 33, and the self-locking retractor 1 automatically locks the length to prevent the body from continuing to move forward.

[0050] When an occupant assumes a supine position at a large angle, forward and backward sliding is the primary cause of injury. At this point, the anti-slip restraint 32 tightens around the occupant's hips, forming a rigid connection with the occupant. Because the system is connected to multiple anchor points above and below it, regardless of whether the occupant slides forward or backward, the four anchor points located behind the sliding force can provide sufficient tension to prevent further sliding. Because the entire restraint system is a continuous unit with multi-directional automatic tightening capabilities, sliding action will cause the system to tighten even more, thereby protecting the occupant's safety.

[0051] To release the restraint system, simply press the unlock button 27 to pop out the movable locking plate, and the quick-release lock buckle 2 will be pulled up and retracted. The entire system is easy to put on and take off, comfortable to use, and has a good protective effect.

[0052] Alternatively, a quick-release buckle 2 with a single movable locking plate 29 can be used. The overall positioning of the restraint strap is the same as in the previous embodiment, with the only difference being that the movable locking plate on one side is replaced with a connection point integral with the body 21 of the quick-release buckle 2, i.e., the anti-slip restraint strap connection point 28.
