Description

Automobile safety belt structure

Technical Field

The present invention relates to safety belts in the interior of automobiles; in particular to an automobile safety belt structure.

Background

With the wide spread of automobiles, automobile safety has become a central priority. Seat belts have been available before automobile discovery, in 1885, when the use of a carriage was common in europe, the seat belt was simply to prevent the passenger from falling off the carriage. By 1910 the appearance of seat belts began on airplanes. In 1922, sports cars in a racing car park began to use safety belts, and in 1955, ford cars began to be equipped with safety belts, and the safety belts in this period generally mainly comprise two-point safety belts. In 1955, aircraft designers worked with Nerns to Walvo automotive corporation and invented a three-point seat belt. In 1963, volvo car began registering the three-point seat belt of nieers and was installed in a self-owned car. In 1968, the united states of america stipulates that the seat belt should be installed in the seat facing forward in a car, and developed countries such as europe and japan also have successively stipulated that the seat belt should be worn by the passenger of the car. The most widely used today is the three-point harness.

The most widely used three-point harness construction is currently available. Among the various types of seat belts, there is a type of seat belt in which the practicality, comfort, and occupant restraint are combined fairly well. Currently, the main components of a safety belt include:

(1) The webbing is a tape woven from synthetic fibers such as nylon or polyester and having a width of about 50mm and a thickness of about 1.2mm, and the properties such as strength and elongation required for a seat belt are achieved by a weaving method and heat treatment according to the application. It is also the part that absorbs the conflicting energy. There are different requirements for the performance of safety belts from national legislation.

(2) The retractor is a device which adjusts the length of a safety belt according to the sitting posture, the stature and the like of a passenger and winds up a mesh belt when not in use. It is divided into ELR (environmental Locking Recractor) and ALR (Automatic Locking Recractor).

(3) The fixing mechanism comprises a belt buckle, a bolt, a fixing pin, a fixing seat and the like. Buckles and latches are devices that fasten and unfasten seat belts. One end of the webbing is fixed to the vehicle body and is referred to as a fixed plate, the vehicle body fixed end is referred to as a fixed seat, and the fixing bolt is referred to as a fixing bolt. The position of the shoulder belt fixing pin has a great influence on the convenience in fastening the belt, and therefore, in order to be suitable for passengers of various sizes, an adjustable fixing mechanism is generally selected and used, and the position of the shoulder belt can be adjusted up and down.

The specific working principle is as follows: the retractor functions to store webbing and lock webbing pull-out, which is the most complex mechanical part of the belt. The retractor is internally provided with a ratchet mechanism, so that under normal conditions, a passenger can freely pull the mesh belt on the seat at a constant speed, but when the mesh belt is continuously pulled out from the retractor and stops once or when a vehicle meets an emergency state, the ratchet mechanism can perform locking action to automatically lock the mesh belt, and the mesh belt is prevented from being pulled out. The mounting fixtures are tabs, inserts, bolts, etc. connected to the vehicle body or seat member, and their mounting positions and firmness directly affect the safety belt protection effect and comfort of the occupant.

The prior safety belt has a part of defects while protecting passengers and improving the comfort of the passengers. For example, when the occupant is unconscious due to an accidental collision, the seat belt tightly fixes the occupant to the seat. If the temporary rescue personnel cannot touch the safety belt lock to unlock the safety belt or the lock is not impacted, and no proper cutting tool is available on hand, the passengers cannot be rescued from the accident vehicle in time. Meanwhile, when the vehicle is driven to go out, the rope is available in a cordless manner in the face of emergency situations such as unexpected water fall and the like which need the rope.

With the widespread use of automobiles, automobile safety has become a central issue, see fig. 1-4. Seat belts have been available before automobile invention, in 1885, when the use of a carriage was common in europe, the seat belts were simply to prevent passengers from falling off the carriage. By 1910, safety belts began to appear on airplanes. In 1922, sports cars in a racing car park began to use safety belts, and in 1955, ford cars began to be equipped with safety belts, and the safety belts in this period generally mainly comprise two-point safety belts. The three-point seat belt was invented in 1955 after the work of the aircraft designer nielsen to wolfo automobile company. In 1963, volvo automobile company began registering Neires' three-point seat belts for automobiles and assembled them on self-produced automobiles. In 1968, the U.S. stipulated that safety belts should be installed in forward facing seats of passenger cars, and developed countries such as europe and japan also set up regulations that safety belts should be worn by car occupants. The most widely used today is the three-point harness.

The most widely used three-point harness construction is currently available. Among the various types of seat belts, there is a type of seat belt in which the practicality, comfort, and occupant restraint are combined fairly well. Currently, the main components of a safety belt include:

(1) The webbing is a tape woven from synthetic fibers such as nylon or polyester and having a width of about 50mm and a thickness of about 1.2mm, and the properties such as strength and elongation required for a seat belt are achieved by a weaving method and heat treatment according to the application. It is also the part that absorbs the conflicting energy. There are different requirements for the performance of safety belts from national regulations.

(2) The retractor is a device which adjusts the length of a safety belt according to the sitting posture, the stature and the like of a passenger and winds up a mesh belt when not in use. It is divided into ELR (environmental Locking Recractor) and ALR (Automatic Locking Recractor).

(3) The fixing mechanism comprises a belt buckle, a lock tongue, a fixing pin, a fixing seat and the like. Buckles and latches are devices that fasten and unfasten seat belts. One end of the webbing is fixed to the vehicle body and is referred to as a fixing plate, the vehicle body fixing end is referred to as a fixing seat, and the fixing bolt is referred to as a fixing bolt. The position of the shoulder belt fixing pin has a great influence on the convenience in fastening the belt, and therefore, in order to be suitable for passengers of various sizes, an adjustable fixing mechanism is generally selected and used, and the position of the shoulder belt can be adjusted up and down.

The specific working principle is as follows: the retractor functions to store webbing and lock webbing pull-out, which is the most complex mechanical part of the belt. The retractor is provided with a ratchet mechanism inside, so that under normal conditions, a passenger can freely pull the mesh belt on the seat at a constant speed, but when the mesh belt is continuously pulled out from the retractor and stops or when the vehicle meets an emergency state, the ratchet mechanism can perform locking action to automatically lock the mesh belt, and the mesh belt is prevented from being pulled out. The mounting fixture is a lug, an insert, a bolt, etc. connected to the vehicle body or a seat member, and their mounting position and firmness directly affect the safety belt protection effect and the comfort of the occupant.

The prior safety belt has a part of defects while protecting passengers and improving the comfort of the passengers. For example, when the occupant is unconscious due to an accidental collision, the seat belt tightly fixes the occupant to the seat. If the temporary rescue personnel cannot touch the safety belt lock to unlock the safety belt or the lock is not impacted, and no proper cutting tool is available on hand, the passengers cannot be rescued from the accident vehicle in time. Meanwhile, when the vehicle is driven to go out, the rope is available in a cordless manner in the face of emergency situations such as unexpected water fall and the like which need the rope.

Therefore, based on the above reasons, we summarize the existing technical problems as follows: when the accident collision causes the comatose of the passenger, the safety belt tightly fixes the passenger on the seat. If the temporary rescue personnel cannot touch the safety belt lock to unlock the safety belt or the lock is not impacted, and no proper cutting tool is available on hand, the passenger cannot be rescued from the accident vehicle in time.

Accordingly, the present invention provides a new structure of a safety belt for a vehicle; by adopting the unique weaving mode, the safety belt can become a rope with the length of about ten meters only by detaching the connecting rod when the danger occurs so as to meet the use requirement in the accident situation.

Specifically, the seat belt provided in the present embodiment includes a first mesh 100, wherein one end of the first mesh 100 is connected to a reel 200; the function of the reel 200 here is to store the first web 100 and to lock the first web 100 from being pulled out, which is the most complex mechanical element in a harness. The inside of the reel 200 is a ratchet mechanism, so that the passengers can pull the first net 100 at a constant speed on the seat under normal conditions, but when the continuous pulling-out process of the first net 100 from the reel 200 is stopped or when the vehicle encounters an emergency, the ratchet mechanism can perform a locking action to automatically lock the first net 100, so as to prevent the first net 100 from being pulled out. The mounting fixture is a tab, an insert, a bolt, etc. connected to the vehicle body or the seat member.

The other end of the first mesh 100 is connected with the second mesh 400 through a connecting rod 300; second web 400 is in turn connected to a third further web 600 by means of a further link 300, where third web 600 has the same structure as first web 100; the end of the third webbing 600 is fixed to the vehicle body by a fixing piece 500, thereby constituting the webbing system of the seat belt of the present embodiment.

According to the above-mentioned structure of the seat belt for a vehicle, the first webbing 100 is woven by at least one webbing; in a specific embodiment, the toughness and strength of the first net 100 as an important component of the connecting rod 300 and the reel should be effectively ensured, so that the toughness and strength of the first net can be effectively ensured while ensuring comfort by adopting a weaving manner, and safety can be effectively ensured when a passenger uses the first net specifically.

Further, in the present embodiment, according to the above-described structure of the seat belt for the vehicle, the first mesh 100 mentioned herein is formed by weaving a woven belt in the warp and weft directions. It will be appreciated that in order to improve the comfort and flexibility of first web 100, and also to improve its strength, the entire first web 100 is effectively uniformly distributed and subjected to more uniform forces during use by using a weaving method, particularly a warp weaving method and a weft weaving method.

The weave pattern may be varied, i.e., the weave pattern of first web 100 may be varied, two of which are briefly described herein in connection with the schematic drawings for ease of understanding.

The first method comprises the following steps: referring to fig. 5, in the present embodiment, according to the above-described structure of the vehicle seat belt, each of the warp threads and each of the weft threads formed in the first mesh 100 are interlaced and woven.

That is, the weaving manner adopted herein is respectively staggered weaving, such as radial lines 1, radial lines 2, radial lines 3, radial lines 4 \8230; then weft threads 1, 2, 3 and 4 are distributed and arranged in the weft direction for 8230, 8230; thus, in the specific weaving, the detailed interlacing weaving is that the warp threads 1 are lapped over the weft threads 1, then are continuously drawn downwards and pass under the weft threads 2, then are continuously drawn upwards and lapped over the weft threads 3, and then are continuously drawn downwards and pass under the weft threads 4 \8230; in this way, the radial lines 1 respectively penetrate through each weft line one above the other, and then a radial weaving structure is formed; then radial threads 2 are formed, the knitting traction direction of the radial threads 2 is opposite to that of the radial threads 1, and the specific knitting direction is as follows: the warp thread 2 is drawn downwards and passes below the weft thread 1, then continues to be drawn upwards and is overlapped above the weft thread 2, then continues to be drawn downwards and passes below the weft thread 3, and then continues to be drawn upwards and is overlapped above the weft thread 4 \8230; thus, the radial lines 2 respectively penetrate through each weft line one by one, and a radial weaving structure is formed; similarly, the radial lines 3 respectively penetrate through each weft line from top to bottom, and the weaving direction is the same as that of the radial lines 1; the warp threads 4 pass through each weft thread one after the other, and the weaving direction is identical to that of the warp threads 2.

And the second method comprises the following steps: referring to fig. 6, in the present embodiment, according to the above-described structure of the vehicle seat belt, each of the warp threads formed in the first mesh 100 is woven by interlacing and winding with a plurality of weft threads, respectively, or each of the weft threads is woven by interlacing and winding with a plurality of warp threads.

That is, the weaving mode adopted here is a plurality of staggered weaves, such as 8230; for example, the weaving mode adopts a weaving mode that radial lines 1/2/3/4/5/6/7/8 are distributed and arranged in the radial direction; then weft lines 1/2/3/4/5/6/7/8 \8230 \/8230; thus, in the specific weaving, the detailed interlacing weaving is that the radial line 1 is lapped above the latitudinal line 1/2, then is continuously drawn downwards and passes below the latitudinal line 3/4, then is continuously drawn upwards and lapped above the latitudinal line 5/6, and then is continuously drawn downwards and passes below the latitudinal line 7/8 \8230; thus, the radial lines 1 pass through every two weft lines one above the other, and a radial weaving structure is formed; then radial threads 2 are formed, the knitting traction direction of the radial threads 2 is opposite to that of the radial threads 1, and the specific knitting direction is as follows: the warp thread 2 is drawn downwards and passes below the weft thread 1/2, then continues to be drawn upwards and overlaps the upper part of the weft thread 3/4, then continues to be drawn downwards and passes below the weft thread 5/6, and then continues to be drawn upwards and overlaps the upper part of the weft thread 7/8 \8230; thus, the radial lines 2 pass through every two weft lines one by one, and a radial weaving structure is formed; similarly, the 3/5/7 of the radial line passes through every two weft lines one above the other, and the weaving direction is the same as that of the radial line 1; the warp threads 4/6/8 pass through every two weft threads one after the other, and the weaving direction is identical to that of the warp threads 2.

In the above embodiment, each radial line passes through every two latitudinal lines one after the other; in other embodiments, each warp line fits equally across every three or four or five of the plurality of weft lines, one next to the other.

In other embodiments, a plurality of radial lines, such as every two, or three, or four, or five, may also be equally adapted to pass over each latitudinal line, one after the other.

By weaving the first net 100 in the above weaving manner, comfort and reliability of the first net 100 can be effectively ensured.

One end of the first web 100 is positioned in the reel 200 and the other end is wound around the connecting rod 300. In this embodiment, the link 300 is used as an important connecting component, and the link 300 can be disassembled, after which the second net 400 can be unfolded to form a webbing rope (the specific structure of the second net 400 will be described later). How to ensure reliable and quick disassembly of the connecting rod 300 is therefore a major issue.

Thus, in this embodiment, connecting rod 300 may be designed to be frangible, i.e., connecting rod 300 may serve as an effective connector to connect first web 100 and second web 400 to one another during normal use; however, in case of danger or economic rescue, the connecting rod 300 can be quickly cut off and separated from the connection with the first net 100 and the second net 400, and the detachment is completed.

The connecting rod 300 can be designed into another structure, and in our conception, the connecting rod 300 is designed into a structure with a rod-shaped middle part and round head-shaped two ends; specifically, it is understood that the connecting rod 300 herein has a rod-shaped body 301 and a spherical head ball 302; the head balls 302 are arranged in two numbers and are respectively positioned at the left end and the right end of the body 301; in order to secure detachability of the entire link 300; the head ball 302 is designed to be separable from the body 301; thus, during the specific use process, only the two head balls 302 need to be quickly detached from the body 301.

Specifically, a screw may be designed on each ball head 302, and the screw is provided with an external thread; then, threaded holes are designed on the left end face and the right end face of the body 301; in the assembling process, the screw rod is directly screwed into the threaded hole, so that the two head balls 302 are assembled with the body 301; and if he encounters an emergency, the passenger simply applies force to rotate the two head balls 302 and then releases the second netting 400 from the link 300 to form a rope.

That is, in the present embodiment, the proposed second net 400 is woven from at least one webbing, the link 300 is configured to be detachable, and the second net 400 can be unfolded into a webbing rope after the link 300 is detached.

In this embodiment, according to the above-mentioned structure of the car seat belt, the second mesh 400 in this embodiment is formed by connecting a mesh a and a mesh B by stitches, and a knot is reserved as a webbing knot, and the webbing knot is configured to prevent the tongue from dropping. That is, in this embodiment, second web 400 is made up of two portions, specifically, web a and web B, joined by a seam; meanwhile, a section is reserved at the connecting position to serve as a braid knot, and the braid knot is configured to prevent the bolt from falling down.

In this embodiment, according to the above automobile safety belt structure, the mesh a and the mesh B in this scheme are formed by weaving two woven belts in the radial direction and the latitudinal direction.

It can be understood that the net a is formed by weaving two weaving belts; meanwhile, the net B is also woven by two weaving belts; in the weaving process, the two weaving belts are woven in a radial direction and a weft direction.

It should be noted that, in the first mesh 100, a weaving belt is woven by interlacing the warp direction and the weft direction; however, in the mesh a and the mesh B, two knitting tapes are knitted by using the warp and weft directions, respectively. This is also the point at which second web 400 differs from first web 100.

In this embodiment, according to the above-described structure of the automobile seat belt, the knitting net a and the knitting net B in this embodiment are knitted in the same manner.

In the present embodiment, according to the above-mentioned structure of the car seat belt, since the weaving manner of the woven net a is the same as that of the woven net B, in order to facilitate the description, the structure of the woven net a is mainly described in the present embodiment; the person skilled in the art can derive from the structure of the netting a and, as a matter of course, from the structure of the netting B. In the scheme, the radial lines in the mesh A are sequentially arranged and respectively bypass the connecting rod 300; the weft threads in the woven net A penetrate through the radial threads in the woven net A in an up-and-down staggered mode.

The upper and lower interleaving can be understood as that each is interleaved with each other, or multiple is interleaved; in describing the structure of first web 100, it is described in detail that if weaving is performed, therefore web a and web B herein may also be woven in this manner.

Such as: radial lines 1, radial lines 2, radial lines 3, radial lines 4 \8230; then weft threads 1, 2, 3 and 4 are distributed and arranged in the weft direction for 8230, 8230; thus, in the specific weaving, the detailed interlacing weaving is that the warp threads 1 are lapped over the weft threads 1, then are continuously drawn downwards and pass under the weft threads 2, then are continuously drawn upwards and lapped over the weft threads 3, and then are continuously drawn downwards and pass under the weft threads 4 \8230; in this way, the radial lines 1 respectively penetrate through each weft line one above the other, and then a radial weaving structure is formed; then, the radial line 2 is formed, the knitting traction direction of the radial line 2 is opposite to the direction of the radial line 1, and the knitting directions of the radial lines 3 above and below are the same as the radial line 1 in the same manner; the knitting direction of the radial lines 4 on the next layer is the same as that of the radial lines 2; radial lines 1, 3, 5, 7 and 9' \8230, wherein the weaving mode of the singular radial lines is the same; while the radial lines 2, 4, 6, 8, 10, 82308230the even radial lines are woven in the same manner.

Similarly, the weave used herein is a plurality of interlaced weaves, such as radial lines 1/2/3/4/5/6/7/8/9 \8230; 8230; for example; then weft threads 1/2/3/4/5/6/7/8 \8230; 8230; are distributed and arranged in the weft direction; thus, in the specific weaving, the detailed interlacing weaving is that the warp threads 1 are lapped over the weft threads 1/2/3, then are continuously drawn downwards and pass under the weft threads 4/5/6, then are continuously drawn upwards and lapped over the weft threads 7/8/9, and then are continuously drawn downwards and pass under the weft threads 10/11/12, \8230; in this way, the radial lines 1 pass through every three weft lines one above the other, and a radial weaving structure is formed; then radial threads 2 are formed, the knitting traction direction of the radial threads 2 is opposite to that of the radial threads 1, and the specific knitting direction is as follows: the warp thread 2 is drawn downward and passes under the weft thread 1/2/3, then continues to be drawn upward and overlaps the weft thread 4/5/6, then continues to be drawn downward and passes under the weft thread 7/8/9, then continues to be drawn upward and overlaps the weft thread 10/11/12 82308230; this will cause the warp threads 2 to pass through every third weft thread one after the other, thus forming a warp knit structure.

Of course, there are also woven structures, such as, for example, the radial lines 1/2/3/4/5/6/7/8/9 arranged in a radial direction 8230; 8230; then weft threads 1/2/3/4/5/6/7/8 \8230; 8230; are distributed and arranged in the weft direction; thus, in the specific weaving, the detailed interlacing weaving is such that the warp threads 1/2/3 overlap the weft threads 1/2/3, then continue to be drawn down and pass under the weft threads 4/5/6, then continue to be drawn up and overlap over the weft threads 7/8/9, then continue to be drawn down and pass under the weft threads 10/11/12 \8230; thus, 1/2/3 of the radial lines simultaneously pass through every three weft lines one above the other, and a radial weaving structure is formed; then radial lines 4/5/6 are formed, the knitting traction direction of the radial lines 4/5/6 is opposite to the direction of the radial lines 1/2/3, and the specific knitting direction is as follows: the warp threads 4/5/6 are drawn down and pass under the weft threads 1/2/3, then continue to be drawn up and overlap over the weft threads 4/5/6, then continue to be drawn down and pass under the weft threads 7/8/9, then continue to be drawn up and overlap 8230above the weft threads 10/11/12, \8230; this will allow the warp yarns 4/5/6 to pass through every third weft yarn at a time, thereby forming a warp knit structure.

Meanwhile, in the embodiment, according to the above-mentioned automobile safety belt structure, the weft threads in the woven mesh a in the present scheme are composed of a first strand 401 and a second strand 402; the first strands 401 and the second strands 402 are respectively and sequentially crossed to penetrate through the radial lines of the mesh A; the first and second strands are then recombined into weft threads in the web a.

Here, after the two connecting rods 300 are disassembled, the second net 400 can be quickly changed into a braided belt for emergency use.

The technical scheme has the advantages that in the scheme, passengers can be effectively protected during normal use, and great promotion effect on improving comfort of the passengers is achieved; but after the emergency situation appears, the passenger can tear open or break off the connecting rod here, take out the connecting rod after, just can take out the second knitmesh in the middle, and the second knitmesh loses the support and through simple pulling and combing, just can become a rope of about ten meters to make things convenient for passenger's urgent use.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures.
