Description

  The present invention relates to an ottoman device for a vehicle.

  Patent Document 1 discloses a ottoman device for a vehicle, which pulls a lower leg (spine part) of an occupant placed on an ottoman main body backward by sliding the ottoman main body backward or rearward and upward at the time of a frontal collision of the vehicle.

  In the technology described in Patent Document 1, the lower leg of the occupant is pulled backward with the slide of the ottoman main body, thereby avoiding strong interference between the vehicle compartment front (instrument panel, toe board, etc.) and the lower leg of the occupant. it can. On the other hand, since the ottoman main body after the slide movement restricts the forward movement of the occupant's thighs, it is suppressed that the occupant is thrown forward.

JP 2005-238931 A

  However, in the prior art described in Patent Document 1, it is considered that when the distance between the lower leg of the occupant and the instrument panel or the like is long, the inertial movement of the occupant at the late stage of the collision can not be suppressed. Furthermore, as automatic driving of passenger cars advances, the aspect of using a vehicle seat by turning it back and forth is also assumed. In this case, at the time of a frontal collision of the vehicle, it is difficult to restrict the lower leg of the occupant who is about to move by inertia by the ottoman main body after the slide movement. For this reason, it may be assumed that the upper body of the occupant may slip above the seat, and there is room for improvement in this point.

  In view of the above facts, the present invention restrains the shin part of the occupant at the time of a vehicle collision even when the distance between the lower leg of the occupant and the instrument panel etc. is long or when the vehicle seat is used in reverse. It is an object of the present invention to obtain an ottoman device for vehicles that can

  The ottoman device for a vehicle according to the first aspect of the present invention is disposed on the seat front side of a seat cushion in a vehicle seat, is provided with an ottoman main body on which a shin part of an occupant is placed, and the ottoman main body A side support portion for positioning the left and right shins of the occupant placed in the seat width direction, and the side support portion is provided to cover the fronts of the occupant's left and right shins by inflating and deploying, and the ottoman main body And the side support portion encloses the shin portion of the occupant, and the airbag portion suppresses movement of the shin portion of the occupant from the position where positioning by the side support portion is performed in the acting direction of the inertial force. doing.

  According to the first aspect of the present invention, the ottoman main body on which the shin part of the occupant is placed is disposed on the seat front side of the seat cushion. The ottoman main body is provided with side support portions for positioning the left and right shins of the occupant placed on the ottoman main body in the seat width direction. The side support portion is provided with an air bag portion, and the air bag portion covers the front surfaces of the left and right shins of the occupant by inflating and deploying. Therefore, the shin part of the occupant is surrounded by the ottoman main body, the side support part, and the air bag part. As a result, the airbag unit suppresses the movement of the shin of the occupant from the position where the side support unit is positioned in the acting direction of the inertial force. Thus, at the time of a vehicle collision, it is possible to restrain the shin of the occupant who is about to move by inertia, and it is possible to suppress the movement of the waist of the occupant.

  As described above, the ottoman device for a vehicle according to the present invention has an excellent effect of being able to restrain the shin part of the occupant at the time of a vehicle collision.

First Embodiment
The vehicle ottoman device 10 according to the first embodiment will be described below with reference to FIGS. 1 to 7. In addition, arrow FR suitably described on the drawing has shown the vehicle front side, arrow UP has shown the vehicle upper side, and arrow OUT has shown the vehicle width direction outer side. Moreover, when it demonstrates only using front and back, up and down, and left and right directions, unless indicated otherwise, it indicates the left and right in the front and rear direction of the vehicle front and rear, up and down in the vehicle vertical direction, and the front in the vehicle front and rear direction. I assume. Further, the seat longitudinal direction of the vehicle seat 12 coincides with the vehicle longitudinal direction, and the seat width direction of the vehicle seat 12 coincides with the vehicle lateral direction. In the present embodiment, the direction of the vehicle and the direction of the seat are the same unless otherwise noted.

  As shown in FIGS. 1 and 2, the vehicle seat 12 includes a seat cushion 14 for supporting the waist L (here, including the buttocks) and the thigh D of a seated occupant, and a rear end of the seat cushion 14. And a headrest 18 provided at the upper end of the seatback 16 to support the head H of the occupant. The vehicle seat 12 is rotatably supported on the floor of the passenger compartment by a seat cushion 14 via a rotating device (not shown). As a result, the vehicle seat 12 directs the front of the vehicle to the front seat position (shown by a solid line in FIG. 2) and the back facing seat position (the front direction in FIG. 2) to the vehicle floor. It can be set to either of two dots and dashes). The vehicle seat 12 is a passenger seat of a right-hand drive vehicle.

Furthermore, the vehicle ottoman device 10 is mounted on the vehicle seat 12 described above. The ottoman device 10 for a vehicle is provided on an ottoman main body 20 that lifts and supports from below the shin S of an occupant seated on the vehicle seat 12, and both sides and the center of the ottoman main body 20 in the vehicle width direction. A side support portion 24 and an air bag portion 40 provided on each of the side support portions 24 on both sides in the vehicle width direction of the ottoman main body 20 are configured. The ottoman main body 20 is provided on the front side of the seat cushion 14 so as to be rotatable about an axis in the vehicle width direction. The ottoman main body 20 is supported by an actuator (not shown) disposed on the lower surface side of the seat cushion 14, and the actuator is electrically connected to the ECU 60 mounted on the vehicle. Then, the actuator is driven by the electrical control of the ECU 60 to push up the ottoman main body 20 from the lower surface thereof. Thus, the ottoman main body 20 is pivoted relative to the seat cushion 14 about the axis in the vehicle width direction. Specifically, as shown in FIG. 3, the inclination angle θ of the ottoman main body 20 from the axis V perpendicular to the cabin floor is a predetermined angle θmax (uppermost point) from the initial angle θ ₀ (lowermost position) It is possible to set the desired angle up to the position). When the inclination angle θ of the ottoman body 20 is set to θmax, the legs of the seated occupant are placed on the seat cushion 14 and the ottoman body 20 with almost no bending.

  Supplementally, in each drawing, a dummy (doll) for a collision test is shown seated on the seat cushion 14 of the vehicle seat 12 as a model of an occupant to be protected. The dummy is seated in a standard seating posture determined by the collision test method, and the vehicle seat 12 is located at a reference setting position corresponding to the seating posture. Hereinafter, the dummy is regarded as an occupant and is referred to as “occupant P”.

  The ottoman main body 20 has a structure in which a pad is covered with a metal frame such as aluminum (not shown) and has a substantially rectangular plate shape in plan view. Further, the upper end portion of the frame is rotatably supported on the seat front side of the seat cushion 14 about an axis in the vehicle width direction. On the other hand, a footrest 22 supporting the sole of the occupant P is connected to the lower end portion of the frame. The footrest 22 is in the form of a plate which is erected substantially vertically upward with respect to the ottoman main body 20 from the lower end portion of the ottoman main body 20.

  The seat upper surface of the ottoman main body 20 is provided with a side support portion 24 for positioning the left and right shins S of the occupant placed on the ottoman main body 20 in the seat width direction. The side support portion 24 positions the seat portion S of the left foot in the seat width direction with the leg portion S of the occupant P placed on the ottoman main body 20, and the seat width direction of the shin portion S of the right foot And a side support portion 24R that performs positioning.

  As shown in FIGS. 1 and 4, the side support portion 24L includes a pair of plates 24L-1 and 24L-2 disposed on the left side with respect to the center of the upper surface of the ottoman main body 20 as viewed from the occupant P. ing. The plates 24 </ b> L- 1 and 24 </ b> L- 2 are erected substantially perpendicularly to the upper surface of the ottoman main body 20. Specifically, the plate 24L-1 is disposed along the left side of the ottoman main body 20 in the sheet width direction. On the other hand, the plate 24L-2 is disposed substantially parallel to the plate 24L-1 at a predetermined interval in the vehicle width direction. Thus, when the occupant P is seated on the vehicle seat 12, the left shin S of the occupant P is inserted between the plate 24L-1 and the plate 24L-2.

  On the other hand, the side support portion 24R is configured of a pair of plates 24R-1 and 24R-2 disposed on the right side with respect to the center of the upper surface of the ottoman main body 20 when viewed from the occupant P. Similar to the side support portion 24L, the plates 24R-1 and 24R-2 are erected substantially perpendicularly to the upper surface of the ottoman main body 20. Specifically, the plate 24R-1 is disposed along the right side of the ottoman main body 20 in the sheet width direction. On the other hand, the plate 24R-2 is disposed substantially parallel to the plate 24R-1 at a predetermined interval in the vehicle width direction. When the occupant P is seated on the vehicle seat 12, the right shin S of the occupant P is inserted between the plate 24R-1 and the plate 24R-2. In the present embodiment, as shown in FIG. 4, the plates 24L-2 and 24R-2 are disposed close to each other in plan view. The plates 24L-2 and 24R-2 may be integrated into one and disposed substantially at the center of the ottoman main body 20.

  The plates 24L-1, 24L-2, 24R-1, and 24R-2 cover a metal frame 26 (see FIG. 6A) such as aluminum, for example, with a pad (not shown) made of a cushion body. The surface of the pad is covered with the skin 28. Further, on the plates 24L-1 and 24R-1 erected on both sides in the sheet width direction of the ottoman main body 20, an air to be described later between the frame 26 and the skin 28 constituting the plates 24L-1 and 24R-1, respectively. The bag parts 40 are respectively provided. Specifically, an air bag module 42L is accommodated between the frame 26 and the skin 28 on the seat front side of the plate 24L-1 on the right side surface in the seat width direction. On the other hand, an air bag module 42R is accommodated between the frame 26 and the skin 28 on the seat front side of the plate 24R-1 on the left side surface in the seat width direction. Here, a tear line 30 is formed which is broken and broken by a predetermined bag inflation pressure acting on the portions covering the air bag modules 42L and 42R (see FIG. 6). Thus, the epidermis 28 is to be cleaved as the air bag portion 40 inflates and deploys.

  Next, the airbag unit 40 will be specifically described.

  The air bag portions 40 are respectively provided on plates 24L-1 and 24R-1 provided on both sides of the upper surface of the ottoman main body 20 in the seat width direction. The airbag unit 40 provided on the plate 24L-1 is configured of an airbag module 42L, and the airbag unit 40 provided on the plate 24R-1 is configured of an airbag module 42R.

  As shown in FIG. 6, the air bag module 42L includes a box-like module case 48L whose opening is directed to the plate 24L-2 side, a left bag 44, and an inflator 62L. The module case 48L is made of, for example, an iron plate or the like, and has a substantially rectangular box shape having no upper surface. The module case 48L accommodates an inflator 62L that accommodates the left bag 44 in a folded state and supplies the gas to the left bag 44. Further, a stud bolt (not shown) is erected from the inflator 62L, and in a state in which the bottom wall 50 of the module case 48L is interposed, the front end portion of the right side surface in the sheet width direction of the frame 26 of the plate 24L-1 described above. It is tightened with a nut. Thus, the air bag module 42L is attached to the plate 24L-1.

  On the other hand, the air bag module 42R includes a box-like module case 48R whose opening is directed to the plate 24R-2 side, a right bag 46, and an inflator 62R. The module case 48R has a structure similar to that of the module case 48L described above, and the sheet width of the frame 26 of the plate 24R-1 with the stud bolts erected from the inflator 62R interposing the module case 48R. A nut is tightened to the front end of the left side in the direction. The other configuration is the same as that of the air bag module 42L, so the description will be omitted.

  As shown in FIG. 4, the above-described inflators 62L and 62R are electrically connected to an ECU 60 mounted on a vehicle. The ECU 60 is also electrically connected to a collision detection sensor (not shown) that detects a collision of the vehicle. In addition, as a collision detection sensor, the acceleration sensor etc. which detect the acceleration of a vehicle can be utilized, for example. The ECU 60 determines whether or not the vehicle has collided based on a detection signal from a collision sensor (not shown), and operates the inflators 62L and 62R when it is determined that the collision has occurred. In addition, a collision prediction sensor such as a pre-crash sensor for predicting a collision of a vehicle may be electrically connected to the ECU 60, or both of the collision detection sensor and the collision prediction sensor may be electrically connected. Good.

  Here, the left bag 44 is formed into a bag shape by being sewn in a state in which the outer peripheral portions of two airbag base fabrics made of nylon 66 or polyester material are overlapped in the sheet longitudinal direction, as an example. The proximal end is open. The entire inflator 62L is inserted from the proximal end.

  Further, as shown in FIG. 6B, a plurality of straps 54 are sewn to the air bag base cloth inside the bag constituting the left bag 44. The strap 54 is formed, for example, by forming a cloth made of the same polyester material as the airbag base fabric in a rectangular strip shape, and two longitudinal airbag base cloths are provided at both ends in the longitudinal direction. It is joined by sewing on the opposite side of each. The longitudinal length of the strap 54 is set to a length at which the strap 54 exerts a tension upon inflation and deployment of the left bag 44. Therefore, the strap 54 is configured to be bridged between the two front and rear airbag base fabrics overlapped in the front and back direction of the seat when the left bag 44 is inflated and deployed. As a result, when the left bag 44 is inflated and deployed, the left bag 44 is prevented from inflating in the seat longitudinal direction, and the inflation and deployment in the sheet width direction is promoted. Further, in the strap 54, a substantially circular communication hole 56 is formed at a predetermined position in a plan view, and the communication hole 56 rectifies the flow of gas when the left bag 44 is inflated and deployed.

  Thus, when the left bag 44 receives the gas supply, it is extended from the opening of the module case 48L to the right in the sheet width direction. Then, in the inflated and deployed state, the leading end of the left bag 44 is in strong contact with the plate 24L-2, and the leading end of the left bag 44 is buried in the pad that constitutes the surface layer of the plate 24L-2. That is, the left bag 44 extends from the plate 24L-1 to the plate 24L-2 and covers the front surface of the left shin S of the occupant P. On the other hand, the vicinity of the base end of the left bag 44 is sandwiched by the front and rear sides of the module case 48L. As a result, even if the left bag 44 is pressed to the seat front side, the position of the left bag 44 during inflation and deployment is maintained by the module case 48L. That is, in the inflated and deployed state, both the base end portion and the tip portion of the left bag 44 are engaged with the side support portion 24L, and the left bag 44 is further suppressed from being moved from the position at the inflating and deploying It is supposed to be.

  In addition, since the structure of the right bag 46 is the same as that of the structure of the left bag 44 mentioned above, description is abbreviate | omitted.

(Action and fruit)
Next, the operation and effects of the present embodiment will be described.

  In the vehicle ottoman device 10 of the present embodiment, when various sensors (not shown) detect or predict a collision of the vehicle, the ECUs 60 activate the inflators 62L and 62R to generate gas. Then, the gas ejected from the inflators 62L and 62R is supplied to the left bag 44 and the right bag 46. At this time, in the left bag 44, the strap 54 joined inside is stretched along the seat longitudinal direction, and the expansion of the left bag 44 in the seat longitudinal direction is restricted. As a result, the left bag 44 is extended from the plate 24L-1 to the plate 24L-2, and is inflated and deployed so as to cover the front surface of the left shin S of the occupant P. On the other hand, in the right bag 46 as well as the left bag 44, expansion in the seat longitudinal direction is restricted by the strap 54 joined to the inside. Then, the right bag 46 is extended from the plate 24R-1 to the plate 24R-2, and is inflated and deployed so as to cover the front surface of the right shin S of the occupant P. Thus, the shin S of the occupant P is surrounded by the ottoman main body 20, the side support portions 24L and 24R, the left bag 44, and the right bag 46.

By the way, in FIG. 5 (A), the vehicle collides in the front in the state which set the vehicle seat 12 to the front seat position, and set the inclination angle θ of the ottoman main body 20 to the initial angle θ ₀ (lowest point position). A ottoman device 10 for a vehicle is shown. In this case, as shown in FIG. 5B, an inertial force in front of the seat acts on the waist L and the shin S of the occupant P. Accordingly, the left bag 44 and the right bag 46 are pushed forward by the shin portion S of the occupant P. At this time, the positions of the left bag 44 and the right bag 46 during inflation and deployment are maintained by the module cases 48L and 48R, respectively. Therefore, with respect to the load input from the occupant P, a reaction force can be received from the left bag 44 and the right bag 46 (see an arrow R shown in FIG. 5B) to restrain the shin S of the occupant P. As a result, the movement of the lower back L to the seat front side can be suppressed. Furthermore, since the state in which the tip portions of the left bag 44 and the right bag 46 are respectively engaged with the side support portions 24L and 24R is maintained, the restraining force of the shin portion S of the occupant P is improved.

  Next, in FIG. 7A, when the vehicle seat 12 is set to the forward facing seat position and the inclination angle θ of the ottoman main body 20 is set to the predetermined angle θmax (uppermost position), the vehicle collides in the front A vehicle ottoman device 10 is shown. In this case, the lower leg of the occupant P who intends to move by inertia presses the footrest 22 connected to the lower end of the ottoman main body 20 to the front of the seat. At this time, since the shin S of the occupant P is restrained by the left bag 44 and the right bag 46 (see an arrow R shown in FIG. 7A), the knee of the occupant P is bent under an inertial force in the forward direction of the seat. Being suppressed. As a result, it is possible to effectively receive a reaction force from the footrest 22 with respect to a load input from the lower leg of the occupant P who is about to inertially move to the footrest 22. Thereby, the leg restraint power of crew member P by footrest 22 is increased, and it can control movement to the seat front side of waist L by extension.

  Further, FIG. 7B shows the vehicle ottoman device 10 in the case where the vehicle collides in the front with the vehicle seat 12 set to the rearward facing seat position. In this case, the upper body of the occupant P tends to move upward above the seat back 16 because an inertial force for moving the occupant P backward (in front of the vehicle) acts on the occupant P. Here, in the vehicle ottoman device 10 according to the present embodiment, the shin S of the occupant P is surrounded by the ottoman main body 20, the side support portions 24L and 24R, the left bag 44, and the right bag 46. Therefore, the portion from the heel to the toe of the occupant P is engaged with the lower ends of the left bag 44 and the right bag 46, and the upward movement of the shin S is suppressed (arrow shown in FIG. 7B) R)). As a result, the upper body of the occupant P is suppressed from being lifted above the seatback 16, and consequently the head of the occupant P is prevented from contacting the windshield or front header of the vehicle (not shown).

  In addition, in any of the above cases, the left bag 44 and the right bag 46 inflate and deploy so as to cover the front of the shin S of the occupant P, thereby effectively protecting the shin S of the occupant P from a collision object or the like. can do.

  Further, the vehicle ottoman device 10 is provided on the vehicle seat 12 and restrains the shin portion S of the occupant P without depending on other configurations such as an instrument panel provided inside the vehicle. Movement can be suppressed. As a result, space saving and cost reduction can be achieved as compared with the case where an air bag is provided on an instrument panel, a steering column or the like in a vehicle compartment, and the degree of freedom in designing the vehicle interior can be enhanced.

Second Embodiment
Next, a vehicle ottoman device 70 according to a second embodiment will be described based on FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 8, in the ottoman device 70 for a vehicle of the present embodiment, the side support portions 72 are disposed on both sides in the seat width direction of the ottoman body 20. The side support portion 72 is configured of a pair of plates 72L and 72R which are provided vertically to the ottoman main body 20. Specifically, the plate 72L is disposed along the sheet width direction left side portion of the ottoman main body 20, and the plate 72R is disposed along the sheet width direction right side portion of the ottoman main body 20. Thus, in a state where the occupant P is seated on the vehicle ottoman device 70, the left and right shins S of the occupant P are inserted between the plate 72L and the plate 72R. The plates 72L and 72R have a structure in which, for example, a metal frame such as aluminum is covered with a pad (not shown) made of a cushion body, and the surface of the pad is covered with the skin 28.

  Further, an air bag portion 73 is provided on the seat front side of the plate 72L on the right side surface in the seat width direction. The air bag portion 73 is composed of an air bag module (not shown) accommodated between the frame of the plate 72L and the skin 28. The air bag module includes a module case (not shown), an inflator, and a shin part restraint bag 74. In addition, since the structure of this air bag module is the same as that of the structure of the air bag module 42L mentioned above, the description is abbreviate | omitted.

  The shin part restraint bag 74 is extended from the plate 72L to the plate 72R in the inflated and deployed state, and is configured to cover the front surfaces of the left and right shin parts S of the occupant P. At this time, the vicinity of the proximal end portion of the shin portion restraint bag 74 is in a state of being held by the front and rear side portions of the module case. Further, the tip of the shin part restraint bag 74 makes strong contact with the plate 72R and is buried in the pad constituting the surface layer of the plate 72R. That is, both the proximal end and the distal end of the shin restraint bag 74 are engaged with the side support portion 72. Thereby, even if the shin part restraint bag 74 is pushed to the seat front side, the position at the time of inflation deployment of the shin part restraint bag 74 is maintained by the module case. As a result, movement of the shin part restraint bag 74 from the position at the time of inflation and deployment is suppressed.

(Action and effect)
Next, the operation and effects of the present embodiment will be described.

  In the vehicle ottoman device 70 of the present embodiment, at the time of a vehicle collision, an inflator (not shown) activates the inflator to generate gas. At this time, the shin restraint bag 74 inflates and deploys and extends from the plate 72L toward the plate 72R so as to cover the front surfaces of the left and right shins of the occupant P. Thus, the left and right shins S of the occupant P are surrounded by the ottoman main body 20, the side support portion 72, and the shin portion restraint bag 74.

  At this time, the vicinity of the base end portion of the shin portion restraint bag 74 is nipped by the front and rear side portions of the module case constituting the air bag module. Therefore, even if a load is input to the shin part restraint bag 74 from the shin part S of the occupant P who intends to move by inertia, the position of the proximal end part of the shin part restraint bag 74 during inflation and deployment is maintained by the module case. Be done. On the other hand, at the tip of the shin part restraint bag 74, this tip is buried in the pad constituting the surface layer of the plate 72R, and the state of being engaged with the side support portion 72 is maintained. Thereby, even if the shin part restraint bag 74 is pushed to the seat front side, the position at the time of inflation deployment of the shin part restraint bag 74 is maintained by the module case. As a result, movement of the shin part restraint bag 74 from the position at the time of inflation and deployment is suppressed. The other actions are the same as in the first embodiment.
