Description

  The present invention relates to a seat belt for a vehicle seat provided with an energizing member (for example, a member capable of generating heat when energized).

  As this type of seat belt, a seat belt that can be mounted on a vehicle seat is known (see Patent Document 1). This seat belt is a long belt-like member (made of woven fabric), and can cross the seat cushion of the vehicle seat in the width direction and restrain the occupant legs. A ribbon-type heater wire (for example, a strip-shaped surface material provided with a nichrome wire) is incorporated in the seat belt, and is disposed over substantially the entire length of the seat belt. In the known technique, after the seat belt is woven, a ribbon-type heater wire is placed on the surface of the seat belt while being sewn (or bonded) and fixed. The occupant leg can be heated by energizing the heater wire while restraining the occupant leg with the seat belt.

Japanese Utility Model Publication No. 62-153162

  By the way, in the technique of patent document 1, a ribbon type heater wire is sewn (adhered) to the surface of the seat belt, and is fixed so as not to be relatively movable. For this reason, in the structure of a well-known technique, the fixing | fixed location (sewing or adhesion | attachment location) of a heater wire became hard, for example, and the softness | flexibility of the seatbelt tended to be impaired. Further, in the configuration of the known technique, since the load applied to the seat belt is also applied directly to the heater wire, the durability of the heater wire tends to be lowered. The present invention has been devised in view of the above-described points, and a problem to be solved by the present invention is to dispose a current-carrying member on a seat belt with good performance.

  As means for solving the above-described problems, the seat belt of the first invention includes a planar or linear energization member capable of energization and can restrain an occupant on the vehicle seat. And a seatbelt is divided into the 1st site | part which should arrange | position an electricity supply member, and the 2nd site | part adjacent to a 1st site | part. In this type of configuration, it is desirable that the current-carrying member can be disposed on the seat belt with good performance (for example, the seat belt can be disposed without losing the flexibility as much as possible).

  Therefore, in the present invention, the seat belt includes a holding portion that holds the energizing member while allowing the energizing member to move relative to the seat belt, and a restricting portion that restricts the energizing member from moving in the direction in which the seat belt extends. . And while having provided a holding part in the 1st part and holding an energization member, it was set as the structure which provides a control part in the 2nd part, and controls that the energization member arranged in the 1st part moves to the 2nd part side. . In the present invention, the current-carrying member can be held at the first portion so as to be relatively movable by the holding portion (the configuration that does not impair the flexibility of the seat belt as much as possible). In addition, the current-carrying member can be held at the first part (appropriate place) by the regulation part of the second part.

  The seat belt of the second invention is the seat belt of the first invention, and is a woven fabric having a bag weave structure composed of a single tissue part and a double tissue part. Therefore, in the present invention, a bag-like holding portion made of a bag weave structure is formed in the first portion, and the energizing member is held therein. And the energization member arranged in the 1st part moves to the 2nd part side by forming the sheet-like regulation part constituted by the single tissue part which makes the double tissue part the closed state in the 2nd part. It was set as the structure which regulates this. In the present invention, the energization member can be disposed on the seat belt with good performance using a bag weave structure (a relatively simple configuration).

  According to the first aspect of the present invention, the energization member can be disposed on the seat belt with good performance. According to the second invention, the current-carrying member can be disposed on the seat belt with good performance with a relatively simple configuration.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In each figure, a reference symbol F is attached to the front of the vehicle seat, a reference symbol B to the rear of the vehicle seat, a reference symbol UP to the upper side of the vehicle seat, and a reference symbol DW to the lower side of the vehicle seat. A vehicle seat 2 in FIG. 1 includes a seat cushion 4, a seat back 6, a headrest 8, and a seat belt 10. Here, the seat back 6 is connected to the seat cushion 4 so as to be able to rise and fall, and the headrest 8 is disposed on the upper portion of the seat back 6 (standing state). The seat belt 10 (described later in detail) is a belt-like member that can restrain the occupant CM. The upper side of the seat belt 10 is disposed so as to be able to be pulled out from a wall body (a retractor not shown) in the vehicle compartment toward the seat back 6 side, and the lower side of the seat belt 10 is fixed to one side of the seat cushion 4. The

[Seat belt]
The seat belt 10 is a belt-like woven fabric composed of a plurality of constituent yarns (warps and wefts described later), and is divided into first portions 1A and 1B that should generate heat and second portions 2A to 2C that do not require heat generation. (See FIGS. 1 and 2). In this embodiment, the seat belt 10 is wound around the occupant CM on the seat from the shoulder of the seat back 6 while being pulled out from the wall in the vehicle compartment (see FIG. 1). In this state, the occupant CM on the seat can be restrained by engaging the seat belt 10 with a buckle (not shown) on the other side of the seat cushion 4 and attaching it. An occupant having a physique ranging from a large occupant (corresponding to AM95 in the SAE standard) to a small occupant (corresponding to JF05 in the SAE standard) can be assumed as the occupant CM. For example, in the present embodiment, the formation positions of the following first parts 1A and 1B and second parts 2A to 2C can be set assuming an occupant CM having an intermediate physique between a large occupant and a small occupant.

(First part, second part)
1st site | part 1A, 1B is formed in the position which can face passenger | crew CM on the basis of a drawer state (refer FIG. 1). For example, one of the first parts (1A) of the present embodiment is formed at a position facing the occupant upper body (portion from the occupant shoulder to the occupant waist). Moreover, the other (1B) of a 1st site | part is formed in the position which faces a passenger | crew leg part. Moreover, 2nd site | part 2A-2C is formed in the seatbelt part except 1st site | part 1A, 1B. For example, one of the second parts (2A) of the present embodiment is formed in a part from the part disposed in the retractor to the first part 1A in the pulled out state. Further, one of the second parts (2B) is formed between the pair of first parts 1A and 1B (a locking part with the buckle). Then, one of the second parts (2C) is formed in a part ahead of the other first part 1B (a seat belt part not facing the occupant leg).

  In the seat belt 10 (withdrawal state) of the present embodiment, the energizing members 30 (details will be described later) are disposed in the first portions 1A and 1B, respectively, and the energizing members 30 are not disposed in the second portions 2A to 2C. (See FIGS. 1 and 2). In this way, the current-carrying member 30 is energized to generate heat and the occupant CM is heated, but in this type of configuration, the current-carrying member 30 is applied to the seat belt 10 with good performance (for example, without losing the flexibility of the seat belt 10 as much as possible). It is desirable that it can be disposed. Therefore, in this embodiment, the current-carrying member 30 is arranged on the seat belt 10 with good performance with the configuration (the holding portion 14 and the regulating portion 16) described later. Hereinafter, each configuration will be described in detail.

[Conductive member]
Here, the energizing member 30 is a flexible strip-shaped face material (substantially rectangular in front view), and is separate from the seat belt 10 before being disposed (see FIGS. 2 and 3). . Examples of the material of this type of face material include soft resin, fabric (woven fabric, knitted fabric, non-woven fabric), and leather (natural leather, synthetic leather). The energizing member 30 of the present embodiment can generate heat when energized. For example, a wire or wiring capable of generating heat is disposed on the surface or inside. Then, by electrically connecting the pair of cables 32a and 32b extending from the end portion (end portion in the longitudinal direction) of the energization member 30 to a power source (not shown), the energization member 30 can be brought into an energized state. In this embodiment, as will be described later, a pair of energizing members 30 are arranged in parallel in the first portions 1A and 1B, respectively (see FIGS. 1 and 2). Each energizing member 30 has a length dimension that follows the length dimension of each first portion 1A, 1B. The width dimension of each energizing member 30 is set to be smaller (less than half) than the width dimension of each of the first portions 1A and 1B, and is housed in a bag-like holding portion 14 described later so as to be relatively movable ( (See FIG. 2).

[Seat belt formation]
In this embodiment, a seat belt 10 (woven fabric having a bag weave structure) is formed by a loom and a scissor (not shown), and a holding portion 14 and a regulating portion 16 described later are formed at appropriate portions (FIGS. 2 and 3). See). Here, as the woven structure of the seat belt 10, various basic structures and changed structures can be used. Typically, a structure (such as a cedar weave structure) having excellent rigidity in the direction in which the seat belt 10 extends (long direction). Is used. Further, the seat belt 10 often requires strength in the longitudinal direction, and typically the weave density in the longitudinal direction is larger than the weave density in the width direction (short direction). In this embodiment, as described later, after warping a plurality of warps (front warp 21u, back warp 21d), wefts 22 are appropriately entangled with these warps (in FIG. 3, for convenience, some front warps and Only the back warp is marked). Next, the seat belt 10 (woven fabric having a bag weave structure) is woven while filling the eyes of the wefts 22.

(Formation of holding part)
The holding portion 14 is a portion that holds the energization member 30 so as to be relatively movable with respect to the seat belt 10, and is formed in the first portions 1 </ b> A and 1 </ b> B (see FIGS. 1 to 3). In the present embodiment, a bag-like holding portion 14 composed of a double tissue portion (11a, 12a) and a single tissue portion (13a) forming a bag weave structure can be formed in each first portion 1A or the like (FIG. 2). And FIG. 3). That is, a pair of double tissue portions (first tissue portion 11a, second tissue portion 12a) is formed in the central portion (the location where each energizing member is disposed) such as the first portion 1A (see FIG. 2). At this time, the first textured portion 11a is formed by capping the eyes of the weft yarn 22 with the scissors while the front warp yarn 21u and the weft yarn 22 are entangled (see FIG. 3). At the same time, the second warp yarn 21d and the weft yarn 22 are entangled with each other, and the eye of the weft yarn 22 is caught to form the second textured portion 12a. In this way, by overlapping and weaving the first tissue portion 11a and the second tissue portion 12a, a pair of double tissue portions (11a, 12a) can be woven at the central portion of the first portion 1A and the like. . Then, the ends of the first structure portion 11a and the second structure portion 12a (the end portions in the short direction of the seat belt 10) are connected to the third structure portion 13a (the front warp yarn 21u, the back warp yarn 21d, and the weft yarn 22). Close with single woven fabric. Further, the center of the first part 1A and the like (the part corresponding to the gap between the pair of energizing members) is closed with the third tissue part 13a. By doing so, a pair of bag-shaped holding portions 14 (bag weave tissue) is formed in the first part 1A and the like, and each energizing member 30 is held therein. Then, by setting the width dimension W1 of the holding portion 14 (dimension in the short direction of the double tissue portions 11a and 12a) larger than the dimension W2 of the energizing member 30, the energizing member 30 can be relatively moved in the holding portion 14. Can be held (see FIG. 2). In the present embodiment, the length dimension of the holding part 14 (the dimension in the longitudinal direction of the double tissue parts 11a and 12a) can be set larger than the dimension W2 of the energizing member 30.

(Formation of the regulation section)
The restricting portion 16 is a portion that restricts the movement of the energizing member 30 in the direction in which the seat belt 10 extends (long direction), and is formed in the second portions 2A to 2C (see FIGS. 1 and 2). . In the present embodiment, the second portion 2B and the like are formed exclusively by the third tissue portion 13a (the planar regulation portion 16 constituted by a single tissue portion) (see FIG. 2). In the present embodiment, a pair of double tissue portions (11a, 12a) having a width narrower than that of the energizing member 30 is formed in a part of the second portion 2B and the like (arrangement position of each cable). As described above, in the present embodiment, the second portion 2B and the like are formed by the third tissue portion 13a (planar regulating portion 16) except for a portion where the pair of cables 32a and 32b are routed. In this way, the end portions (end portions in the longitudinal direction) of each holding portion 14 are partially or entirely closed at the restricting portion 16, and the energization member 30 in the first portion 1 </ b> A or the like is closed. Movement to the second part (2B etc.) side can be regulated. The pair of cables 32a and 32b can be routed outside the seat belt 10 while being arranged in the double tissue portions (11a and 12a), respectively.

[Use of seat belt]
With reference to FIG. 1, the seat belt 10 is pulled out and wound around the occupant CM on the seat from the shoulder of the seat back 6. At this time, in the present embodiment, the holding member 14 holds the energizing member 30 so as to be relatively movable with respect to the first portion 1A and the like, so that the flexibility of the seat belt 10 can be maintained as much as possible (FIG. 2). And a passenger | crew can be heated by making each electricity supply member 30 in 1st site | part 1A etc. generate | occur | produce heat | fever by electricity supply (refer FIG.2 and FIG.3). Further, in the present embodiment, the second part (2A to 2C) is formed in a part arranged in the retractor in the pulled out state and a seat belt part not facing the occupant (see FIG. 1). And it can restrict | limit that the electricity supply member 30 in 1st site | part 1A etc. moves to the 2nd site | part side in the regulation parts 16 of 2nd site | part 2B etc. (refer FIG. 2). For this reason, according to the present embodiment, the movement of each energizing member 30 is restricted so that the second portions 2A to 2C do not generate heat as much as possible, thereby contributing to power saving of the seat.

  As described above, according to the present embodiment, the holding member 14 can dispose the energizing member 30 to the first portions 1A and 1B so as to be relatively movable (the configuration that does not impair the flexibility of the seat belt 10 as much as possible). ). Further, the energizing member 30 can be held at the first portions 1A and 1B (suitable places) by the restricting portions 16 of the second portions 2A to 2C. Further, in the present embodiment, since the energization member 30 can be moved relative to the seat belt 10, the load applied to the seat belt 10 is not directly applied to the energization member 30 (improvement of durability of the energization member). It is a configuration that contributes to In the present embodiment, the holding portion 14 and the regulating portion 16 can be formed by a bag weave structure (a relatively simple configuration). In the configuration (bag weaving structure) of the present embodiment, since the energizing member 30 is covered with the double tissue portions 11a and 12a (structure having a lower woven density than the single tissue portion), the heat of the energizing member 30 is reduced. It can be efficiently transmitted to the passenger CM. For this reason, according to the present embodiment, the energization member 30 can be disposed on the seat belt 10 with good performance.

[Modification 1]
Here, the configuration of the energizing member and the seat belt (holding portion, regulating portion) can take various configurations in addition to the above-described configuration. For example, in the seat belt 10A of Modification 1, the energizing member 30A is a comb-like planar member, and has a base 30a (wide) and a plurality of combs 30b to 30e (narrow) (see FIG. 4). The base 30a is a substantially rectangular portion that is wide toward the short direction of the seat belt 10A. The plurality of comb portions 30b to 30e are belt-shaped portions (substantially rectangular in front view) that are long in the longitudinal direction of the seat belt 10A. In the present embodiment, the plurality of comb portions 30b to 30e are arranged in parallel at equal intervals in the short direction of the seat belt 10A while being connected to the base portion 30a at the base.

  Therefore, in this modification, the base portion 30a and the comb portions 30b to 30e are disposed so as to be relatively movable in the bag woven tissues 11a, 12a, and 13a (bag-like holding portion 14) such as the first portion 1A. At this time, a single tissue portion 13a is formed around the base portion 30a and the comb portions 30b to 30e, and the relative positional relationship between the comb portions 30b to 30e is maintained. Then, by forming the second parts 2A, 2B, etc. by the single tissue part 13a (planar regulation part 16), the energization member 30 in the first part 1A, etc. moves to the second parts 2A, 2B etc. side. Can be regulated.

[Modification 2]
Further, in the seat belt 10B of the second modification, the linear energization member 30B is bent and arranged in a continuous S shape (front view) in the first portion 1A and the like (see FIG. 5). Further, both ends (linear shape) of the energizing member 30B are routed to the outside through the second portion 2B. Here, as the linear energization member 30, a wire having a specific resistance (also referred to as volume resistivity) of 10 ⁰ to 10 ⁻¹² Ω · cm can be typically used. The “specific resistance (volume resistivity)” is a physical property value used for comparing what kind of material is difficult to conduct electricity, and can be measured, for example, according to “JIS C 2525 7.2C”. Examples of this type of wire include wires such as metals and alloys, carbon fiber filaments, and plated wires. The plated wire has a non-conductive or conductive wire (core material) and a metal or alloy plating layer.

  Therefore, in the present modification, continuous S-shaped bag woven tissues 11a, 12a, and 13a (bag-shaped holding portions 14) are provided in the first portion 1A, and the energizing member 30B is disposed therein so as to be relatively movable. At this time, a single tissue portion 13a is formed around the energizing member 30B and the shape (continuous S-shape) is maintained. And by forming 2nd site | part 2A, 2B etc. by the single structure | tissue part 13a (plane-shaped regulation part 16), the electricity supply member 30B in 1st site | part 1A etc. moves to 2nd site | part 2A, 2B etc. side. Can be regulated. At this time, in this modified example, a double tissue portion (11a) that is narrower than the energizing member 30B (continuous S-shaped portion) in a part of the second portion 2B (arrangement positions at both ends of the energizing member). , 12a). And by arranging both ends of the energizing member 30B in the double tissue portions (11a, 12a), both ends can be routed outside the seat belt 10B.

[Modification 3]
Further, the holding part and the restricting part can be constituted by linear members. For example, in the seat belt 10C of the third modification, a pair of current-carrying members 30 (planar shapes) are arranged in parallel with the first portion 1A and the like (see FIG. 6). Further, a plurality of holding portions 14 </ b> A (holding portions made of a plurality of wire rods) are arranged at appropriate intervals in the middle of each energizing member 30 in the longitudinal direction. And each end of 14 A of holding parts is fixed to 1st site | part 1A etc. on the outer side of each energizing member 30, straddling each energizing member 30 in the width direction (short direction) for each holding part 14A. Thus, the energizing member 30 can be held relative to the seat belt 10C by the holding portion 14A so as to be relatively movable.

  Moreover, in this modification, a pair of cables 32a and 32b are arrange | positioned in parallel with the 2nd site | part 2B. And 16 A of regulation parts (regulation part comprised with the some wire) are arrange | positioned across a pair of cables 32a and 32b in these width directions. In this state, both ends of the restricting portion 16 </ b> A are fixed to the second portion 2 </ b> B at an inner position than the energizing member 30. By carrying out like this, it can control that energization member 30B in the 1st part 1A etc. moves to the 2nd part 2A etc. side by regulation part 16A. The wire forming the holding portion 14A and the regulating portion 16A may be formed of the same material as the constituent yarn of the seat belt 10C, or may be formed of a wire material that is more rigid than the constituent yarn.

[Modification 4]
In the fourth modification, a planar seat belt 10D and a covering member 60 are used (see FIG. 7). The covering member 60 is a face member having a width dimension that follows the short direction of the seat belt 10D, and the length dimension thereof is set to be larger than the first part 1A or the like (the end part side of the covering member 60 is the second part). Set to the dimension that protrudes to the side). Examples of the material of the covering member 60 include fabric (woven fabric, knitted fabric, non-woven fabric) and leather (natural leather, synthetic leather). For example, a face material (woven fabric having a low woven density, etc.) having better thermal conductivity than the seat belt 10D. It is desirable that

  Therefore, in this modification, only the both ends in the width direction of the covering member 60 are fixed to the first portion 1A by welding, adhesion, or sewing, while covering the surface of the first portion 1A or the like (non-contained) A fixing portion 62 and a pair of first fixing portions 64 are formed). By doing so, the energizing member 30 can be held relative to the inside while forming the bag-like holding portion 14B with the non-fixing portion 62 and the pair of first fixing portions 64. And the edge part of the length direction of the coating | coated member 60 is fixed to 2nd site | part 2A, 2B side (a pair of 2nd fixing | fixed part 66,68 is formed). In this way, the restricting portion 16B is configured by the pair of second fixing portions 66 and 68, and the movement of the energizing member 30 in the first portion 1A or the like to the second portion 2A or 2B or the like side can be restricted.

[Modification 5]
In addition to the above-described configuration, the seat belt formation method (the method for arranging the energization members) can take various configurations. For example, in Modification 5, after warping a plurality of warps passing between the teeth of the heel 40, wefts are appropriately entangled with these warps (see FIG. 8). Next, the heel 40 is moved, and the seat belt (bag-woven fabric) is woven while filling the eyes of the weft. Here, the brim 40 is a substantially rectangular (hollow) member having a larger width than the seat belt, and a plurality of teeth 42a to 42h (linear) are arranged at equal intervals. Note that the number of teeth of the heel 40 can typically be set according to the number of warp yarns of the seat belt 10.

  In this modification, the width dimension W2 of each energizing member 30 is set to be larger than the gap dimension W3 between adjacent teeth (for example, the teeth 42a and the teeth 42b) of the collar 40. And the electricity supply member 30 of a present Example can be changed into the state which was rounded by the roll shape in the short direction and deform | transformed by the flexibility. And the current-carrying member 30 (roll shape) after the change is maintained while the seat belt (first part) is woven by a jig (not shown) or its own rigidity (appropriate shape retention). Become. And in this modification, it is the structure by which the width dimension becomes small rather than the clearance gap dimension W3 of the adjacent tooth | gear of the collar 40 by making the electricity supply member 30 into roll shape.

  And a pair of electricity supply members 30 are each arrange | positioned in a 1st site | part. In this type of configuration, it is desirable that the energizing member 30 can be disposed on the seat belt 10 with relatively few steps. Therefore, in the present modification, when the first portion is formed, each energizing member 30 is rolled into a short shape in the short direction and deformed, and then in the middle of the movement path of the rod 40 (the position where the first portion is formed). To place. In this state, the first portion is formed while passing the energizing member 30 (roll shape) between the adjacent teeth of the flange 40. In this manner, each energizing member 30 can be arranged in the interior (between the first tissue part and the second tissue part) simultaneously with the formation of each first part. And by making each energizing member 30 into the original state (planar shape) in the first part, the energizing member 30 can be disposed in an appropriate state simultaneously with the creation of the seat belt. In addition, when using a jig for maintaining the state of the energization member 30 (after the change), each energization member is stopped by stopping weaving while the first part is being created (for example, the end side is opened in a bag shape). The jig can be removed from 30.

[Modification 6]
Here, the changed shape of the energization member 30 can be maintained by using various maintenance members 50 (see FIG. 9). For example, in the modified example 6, after the energization member 30 is deformed into a roll shape, the state is maintained by the maintenance member 50 (detailed later). That is, after the energizing member 30 is made into a roll shape, a ring-shaped maintenance member 50 is fitted around the energizing member 30. After weaving the seat belt in this state, the maintenance member 50 is removed, and the energizing member 30 is returned to the original state (planar shape) in the first portion. As described above, in the present modification, the maintenance member 50 can suitably maintain the state after the change of the energization member 30 to smoothly manufacture the seat belt.

[Maintenance member]
As this kind of maintenance member 50, for example, a member having a melting point lower than that of the constituent yarn of the seat belt (such as an adhesive material, a ring material, or a string material) can be used. After weaving the seat belt, various post-treatments (dyeing step, washing step (water washing treatment, steam treatment, etc.), coating step, etc.) are performed. At this time, the current-carrying member 30 naturally returns to the first state by its restoring force, for example, by melting and removing the low-melting-point maintenance member 50 by heat treatment (heat treatment at the time of the dyeing process, etc.). Here, examples of the constituent yarn (material) of the seat belt include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resin or thermosetting resin, and mixed fibers thereof. And it is preferable that the melting | fusing point of the maintenance member 50 is 20 degrees C or less rather than the melting | fusing point of the constituent yarn of a seatbelt. For example, when a polyethylene terephthalate constituent yarn is used, a maintenance member 50 (for example, a polyamide-based, polyester-based, or polyethylene-based fiber) having a melting point of 240 ° C. or lower can be used.

  Further, a water-soluble member (such as an adhesive material, a ring material, or a string material) can be used as the maintenance member 50. Then, the water-soluble maintenance member 50 is dissolved and removed by applying water in the water washing process or the coating process, so that the current-carrying member 30 naturally returns to its original state by its restoring force. Examples of this type of water-soluble maintenance member 50 (material) include cellulose fibers (polyvinyl alcohol fiber, carboxymethyl cellulose, etc.), polyalginic acid fibers, and polyalkylene fibers.

  The seat belt of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments. For example, in the present embodiment, the configuration (shape, dimension, arrangement position, etc.) of the seat belt 10 is illustrated, but the configuration of the member is not intended to be limited. For example, the seat belt can be configured to restrain only the occupant legs, and can also be configured to restrain only the occupant upper body. Further, the seat belt pull-out location can be set at an appropriate position in the vehicle seat or the passenger compartment depending on the configuration of the vehicle. Further, both ends of the seat belt can be fixed to the passenger compartment, and the middle of the seat belt can be locked (attached) to the vehicle seat. And the structure (formation position, number of formation, etc.) of a 1st site | part and a 2nd site | part can be suitably changed according to the structure of a seatbelt.

  Moreover, although the example which uses the electricity supply member 30 as a heater was demonstrated in this embodiment, it can also be used as an electrode of an electrostatic capacitance type sensor. The configuration (shape, dimensions, arrangement position, number of arrangements, etc.) of the energization member 30 can be changed as appropriate according to the shape of the seat belt and the function of the energization member.

  Moreover, in this embodiment, although the structure of the holding | maintenance part 14 (double tissue part 11a, 12a and single tissue part 13a) and the control part 16 (single tissue part 13a) was illustrated, it is not the meaning which limits the structure of these each part. . For example, the configuration (shape, dimensions, etc.) of the holding portion in the first part can be appropriately changed according to the configuration of the energization member. In addition, in the second part, when the cable is not routed, all or part of the second part can be formed by a single tissue part (regulation part) regardless of the place where the cable is routed. In addition, the structure of the holding | maintenance part and control part of a present Example, and the structure of the holding | maintenance part and control part of each modification can be combined suitably.

  Moreover, in the modification 5, although the structure (shape, dimension, etc.) of the collar 40 was illustrated, the structure of a collar can be changed suitably. For example, the tooth of the heel can be made movable, and when the seat belt is woven, the interval between the teeth can be appropriately widened, and the energizing member can be arranged therebetween. Moreover, in the modification 5, the example which made the shape of the electricity supply member 30 roll shape was demonstrated. As long as the energization member can pass between the teeth of the heel, it can be bent or bent to take various shapes. It is also possible to change the direction of the current-carrying member (for example, from a horizontal state to a vertical state) and pass between the teeth of the eyelids.

  The configuration of the present embodiment can be applied to all vehicle seats such as vehicles, airplanes, and trains. The configuration of the vehicle seat can be changed as appropriate.
