An electrical connection portion 138 is provided on the rear side surface of the base 64. The connection unit 138 is connected to a power supply (vehicle-mounted battery) not shown, for example, via an optional cigarette lighter socket or an accessory socket provided in the vehicle interior.
The connection portion 138 is connected to one end side of the power cord 74, and the middle portion of the power cord 74 is disposed inside the base 64. The other end of the power cord 74 is pulled out from a hole provided on the front side of the upper portion of the base 64, and is finally connected to a not-shown massager housed inside the footrest 68.
[1-3-3: footrest table 68
Next, the footrest 68 will be described with reference to fig. 3 and 4.
The footrest 68 includes a massage base 140 connected to the base 64 via a hinge 66, a massage device, not shown, attached to the massage base 140, a cushion material, not shown, housed so as to surround the massage device, and a skin material 142 covering the massage device and the cushion material.
As shown in fig. 4, the 1 st angle adjusting frame 70 and the 2 nd angle adjusting frame 72 are attached to the bottom surface of the base 140 for a massager via hinges 66.
The massage base 140 has a recess 144 in the center of the bottom surface thereof, which can accommodate both the 1 st angle-adjusting frame 70 and the 2 nd angle-adjusting frame 72. For example, fig. 3 shows a state in which the 1 st angle adjustment frame 70 is rotated and fixed to the locking groove 136 of the upper portion of the base 64, and the 2 nd angle adjustment frame 72 is accommodated in the recess 144.
The massager is a ball type massager that performs a powerful massage by being driven by a power supplied through a power cord 74. Preferably the massager has a heating function. However, the present invention is not limited to this, and any massage device may be used as long as it gives a stimulus such as vibration or warmth to the occupant 20. In addition, a massager may not be mounted.
The skin material 142 is, for example, a fabric used as a skin material of the vehicle seat 18, and the kind thereof is not particularly limited.
The convex portion 146, which is raised from the peripheral edge portion in the vicinity of the upper center of the footrest 68, is a portion that covers the massage ball of the massage ball massager, not shown, housed inside the footrest 68 with the skin material 142.
[2: attachment of foot rest 10 to lower track 24
The ottoman 10 and the vehicle seat system 12 including the ottoman 10 according to the present embodiment are basically configured as described above. Next, the operation of attaching the ottoman 10 to the lower rail 24 will be described with reference to fig. 7 to 9.
As shown in fig. 7, in order to attach the ottoman 10 to the lower rails 24, the slide mechanisms 60 are first attached only to the pair of left and right lower rails 24, respectively. Then, the base 64 to which the footrest 68 is attached is placed over the slide mechanism 60 fixed to the lower rail 24 from above the slide mechanism 60.
[2-1: mounting of the slide mechanism 60 to the lower rail 24
The operation of attaching the slide mechanism 60 to the lower rail 24 will be described. As shown in fig. 7, a person who intends to mount the slide mechanism 60 to the lower rail 24 first arranges the slide mechanism 60 above the lower rail 24 such that the shaft 84 of the slide mechanism 60 is parallel to the lower rail 24 and the 2 nd operating element 116 of the 2 nd lever 80 is directed outward in the vehicle width direction.
Specifically, the 1 st operating element 106 of the 1 st lever 78 is hooked by a fingertip other than the thumb, such as an index finger or a middle finger, and the 2 nd operating element 116 of the 2 nd lever 80 is hooked by a fingertip of the thumb, whereby the 1 st operating element 106 and the 2 nd operating element 116 are sandwiched (sandwiched) by one hand. The slide mechanism 60 is disposed above the lower rail 24 with the 1 st operating element 106 and the 2 nd operating element 116 being sandwiched by one hand.
Next, the distance between the index finger and the thumb is shortened, and the 1 st operating element 106 and the 2 nd operating element 116 are moved closer to each other against the elastic force of the spring 82 (the rotational force to expand the 1 st lever 78 and the 2 nd lever 80).
As a result, the 1 st bent portion 110 and the 2 nd bent portion 122 provided at the lowermost ends of the 1 st lever 78 and the 2 nd lever 80 are rotated in directions to approach each other with the shaft 84 as a fulcrum (see fig. 8). As a result, the distance in the vehicle width direction between the front ends of the 1 st bent portion 110 and the 2 nd bent portion 122 is smaller than the width in the vehicle width direction of the groove portion 38 of the lower rail 24.
In this state, the 1 st bent portion 110 and the 2 nd bent portion 122 are inserted inside the groove portion 38 of the lower rail 24. The 1 st bent portion 110 and the 2 nd bent portion 122 enter the groove portion 38 while bending the bending portions 44R, 44L of the rail cover portion 40.
As shown in fig. 8, the housing 76 of the slide mechanism 60 abuts on the rail cover portion 40, and the 1 st bent portion 110 and the 2 nd bent portion 122 reach below the extending portions 36R and 36L of the lower rail 24. At this time, the hand is separated from the 1 st operating member 106 of the 1 st lever 78 and the 2 nd operating member 116 of the 2 nd lever 80.
Thus, the 1 st bent portion 110 of the 1 st lever 78 and the 2 nd bent portion 122 of the 2 nd lever 80 are expanded outward in the vehicle width direction by the elastic force of the spring 82. As a result, as shown in fig. 9, the lock claw 120 of the 2 nd lever 80 is locked in the locking hole 28 of the lower rail 24, and the slide mechanism 60 is reliably fixed to the lower rail 24. Thus, the fitting (mounting) of the slide mechanism 60 to the lower rail 24 is completed. At this time, the 1 st bent portion 110 and the 2 nd bent portion 122 come into contact with the lower ends (bottom portions) of the extending portions 36R and 36L, and function as the falling-off prevention portions.
In fig. 8 and 9, only the left-side slide mechanism 60 of the pair of left and right slide mechanisms 60 in fig. 4 and 7 is shown in a cross-sectional view, and the right-side slide mechanism 60 can be attached to the lower rail 24 by the same operation, and therefore, the description thereof is omitted.
[2-2: mounting of base 64 to slide mechanism 60
The operation of attaching the base 64 to which the footrest 68 is attached via the hinge 66 to the pair of slide mechanisms 60 already attached to the lower rail 24 will be described.
As shown in fig. 4, in order to attach the base 64 to the slide mechanism 60, the fitting convex portions 104, 104 of the base 64 are fitted from above into the fitting grooves 100, 102 of the slide mechanism 60 already attached to the lower rail 24. The fitting projections 104, 104 are locked in the fitting grooves 100, 102, and the base 64 and the footrest 68 connected to the base 64 via the hinge 66 are reliably attached to the slide mechanism 60. Thereby completing the assembly (mounting) of the ottoman 10 to the lower rail 24.
[3: movement of footrest 10
In order to move ottoman 10 to a desired position in the front-rear direction along lower rail 24 after ottoman 10 is attached to lower rail 24, 2 nd lever 80 of slide mechanism 60 is rotated against the elastic force of spring 82 only by hooking 2 nd operating piece 116 of 2 nd lever 80 with a finger.
As shown in fig. 10, the engagement between the locking claw 120 provided at the lower end of the 2 nd lever 80 and the locking hole 28 of the lower rail 24 is released in accordance with the rotation of the 2 nd lever 80. In this state, the slide mechanism 60 is displaced in the front-rear direction along the lower rail 24 with the 2 nd operating element 116 being hooked by the finger, and the footrest 10 can be slid as a whole.
At this time, the 1 st bent portion 110 provided at the lower end of the 1 st lever 78 slides on the extension portion 36L of the lower rail 24. Thereby, the footrest 10 is reliably guided along the lower rail 24.
After the footrest 10 is moved to a desired position, when the finger is separated from the 2 nd operation element 116 of the 2 nd lever 80, the lock claw 120 of the 2 nd lever 80 is expanded inward in the vehicle width direction by the elastic force of the spring 82. As a result, as shown in fig. 9, the lock claw 120 of the 2 nd lever 80 is locked in the locking hole 28 of the lower rail 24, and the slide mechanism 60 is fixed to the lower rail 24 again. As described above, the sliding (movement) of the ottoman 10 is completed.
After the ottoman 10 is fixed at a desired position, the occupant 20 seated in the vehicle seat 18 rotates the footrest 68 to a desired angle. The angle of the footrest 68 is fixed by using the 1 st angle adjustment frame 70 or the 2 nd angle adjustment frame 72, and the footrest 10 is used by driving a massage device (not shown) (see fig. 1 and 11).
[4: removal of ottoman 10 from lower track 24
In order to detach the ottoman 10 from the lower rail 24, the base 64 to which the footrest 68 is attached is lifted up, and the fitting protrusion 104 of the base 64 is pulled out from the fitting grooves 100, 102 of the slide mechanism 60.
At this time, the lower end of the substantially U-shaped cutout portion 134 of the base 64 interferes with the upper end of the 2 nd lever 80 of the slide mechanism 60, but the interference with the 2 nd lever 80 can be avoided by rotating the 2 nd operating element 116 of the 2 nd lever 80 by a certain amount inward in the vehicle width direction. Thereby, the base 64 is detached from the slide mechanism 60.
Next, the slide mechanism 60 attached to the lower rail 24 is displaced in a direction in which the 1 st operating element 106 of the 1 st lever 78 and the 2 nd operating element 116 of the 2 nd lever 80 approach each other by gripping them with a hand. When the 1 st operating member 106 and the 2 nd operating member 116 are lifted up while being sandwiched, the 1 st bent portion 110 and the 2 nd bent portion 122 are pulled out from the groove portion 38 of the lower rail 24. Thereby, the slide mechanism 60 is detached from the lower rail 24, and the detachment of the ottoman 10 from the lower rail 24 is completed.
[5: other methods of attaching and detaching the ottoman 10 to the lower rail 24 ]
In the present embodiment, the base 64 is provided with substantially U-shaped cutout portions 134 at both ends in the vehicle width direction, and a pair of fitting holes 62 communicating with the cutout portions 134. As shown in fig. 3, if the footrest 68 is rotated with respect to the base 64 via the hinge 66 and the angle of the footrest 68 with respect to the base 64 is fixed using the 1 st angle adjustment frame 70 or the 2 nd angle adjustment frame 72, even in a state where the base 64 is attached to the slide mechanism 60, it is possible to insert a hand from above into the fitting holes 62 at both ends in the vehicle width direction.
Therefore, even in a state where the base 64 is attached to the slide mechanism 60, the footrest 68 can be opened (rotated) with respect to the base 64, and the 1 st operating element 106 of the 1 st lever 78 and the 2 nd operating element 116 of the 2 nd lever 80 of the slide mechanism 60 accommodated in the fitting hole 62 can be operated. That is, even in a state where the base 64 and the slide mechanism 60 are integrated, the ottoman 10 can be attached to and detached from the lower rail 24.
[6: summary of the embodiments
In the ottoman 10 and the vehicle seat system 12 including the ottoman 10 according to the embodiment of the present invention, the ottoman 10 shares a pair of lower rails (rail members) 24 extending in the vehicle front-rear direction with the vehicle seat 18, and is movable in the vehicle front-rear direction along the pair of lower rails 24 independently of the vehicle seat 18, and the ottoman 10 includes: a pair of slide mechanisms 60 attached to the pair of lower rails 24 and capable of freely switching between sliding and fixing with respect to the pair of lower rails 24; a base 64 extending in the vehicle width direction of the vehicle and housing the pair of slide mechanisms 60; and a footrest 68 provided at an upper portion of the base 64, and the slide mechanism 60 is provided with a 2 nd rod 80 (rod member) pivotally supported so as to be rotatable in the vehicle width direction.
According to the above configuration, the 2 nd lever 80 that is pivotally supported in the vehicle width direction is provided on at least one of the slide mechanisms 60. By rotating the 2 nd lever 80 in the vehicle width direction, the positions of the lock claw 120 (the locking portion) and the 2 nd bent portion 122 (the sliding portion) provided at the end portion of the 2 nd lever 80 with respect to the lower rail 24 can be easily switched to positions that can be attached to, moved (slid) or fixed with respect to the lower rail 24.
Therefore, the footrest 10 can be moved along the lower rail 24 of the vehicle seat 18 by a simple structure that pivotally supports the 2 nd rod 80 so as to be rotatable in the vehicle width direction, can be fixed to the lower rail 24 at a desired position, and can be easily attached to the lower rail 24. As a result, even when a new vehicle is delivered or purchased, the footrest 10 can be easily and quickly attached to the lower rail 24 later.
The footrest 10 includes a shaft 84 that pivotally supports the 2 nd rod 80 so as to be rotatable in the vehicle width direction, and the 2 nd rod 80 includes a 2 nd operating element (operating portion) 116 on one end side and engaging portions (a locking claw 120 and a 2 nd bent portion 122) on the other end side. Preferably, the locking portions (the locking claws 120 and the 2 nd bent portion 122) of the 2 nd lever 80 are biased outward in the vehicle width direction by the spring 82 wound around the shaft 84.
According to the above configuration, by rotating the 2 nd operating element 116 against the elastic force of the spring 82, the position of the locking portion (the locking claw 120 and the 2 nd bent portion 122) with respect to the lower rail 24 can be easily switched to a position where the locking portion can be detached, slid, or fixed.
The lever member is composed of two levers, and the engaging portion of at least one of the 2 nd levers 80 includes a 2 nd bent portion 122 that is slidable with the lower rail 24, and a locking claw (locking claw portion) 120 that is insertable into an engaging hole (hole portion) 28 formed in the lower rail 24. The 2 nd rod 80 is preferably slidable and fixable on the lower rail 24 by engagement and disengagement of the lock claw 120.
According to the above configuration, the footrest 10 can be slid and fixed by flexibly using the locking hole 28 of the lower rail 24.
Further, it is preferable that the slide mechanism 60 and the base 64 are detachable.
According to the above configuration, since the base 64 can be attached to the slide mechanism 60 after the slide mechanism 60 is attached to the lower rail 24, the ottoman 10 can be more easily attached to the lower rail 24.
Further, the seat leg 48 of the vehicle seat 18 is preferably provided to have a length in the front-rear direction shorter than the seat cushion 50.
According to the above configuration, the occupant 20 can insert a hand from the vehicle width direction (left-right direction) of the seat cushion 50 into the lower side of the seat cushion 50 without being obstructed by the seat legs 48. That is, the occupant 20 can operate the ottoman 10 stored below the seat cushion 50 while remaining seated on the seat cushion 50, which is preferable.
The ottoman 10 of the present embodiment includes a footrest 68 that houses a massager. The pair of lower rails 24 extending in the vehicle front-rear direction are shared with the vehicle seat 18, and are movable in the vehicle front-rear direction along the pair of lower rails 24 independently of the vehicle seat 18.
The ottoman 10 having the leg massage function is desired to be movable to a desired position in the front-rear direction in accordance with the body shape of the occupant 20 and the target region to be massaged (leg or sole). According to the above configuration, by sharing (concurrently serving as) the lower rail 24 of the vehicle seat 18, the ottoman 10 that can be moved to a desired position in the front-rear direction at low cost can be provided.
Further, substantially U-shaped cutout portions 134 are provided at both ends of the base 64 in the vehicle width direction. Therefore, even in a state where the ottoman 10 is stored below the vehicle seat 18, the 2 nd operation element 116 of the 2 nd lever 80 can be easily operated.
[7: modification example
The present invention is not limited to the above-described embodiments, and it is needless to say that various configurations can be adopted based on the contents described in the present specification. For example, as shown in fig. 11, the footrest 68 can be used as a footrest with a built-in massager by placing the sole of a foot on the closed footrest 68 without opening (rotating) the footrest 68.
As shown in the modification example shown in fig. 12, the slide mechanism 160 may be provided with only the 2 nd lever 80 having the locking claw 120 and the 2 nd bent portion 122, without the 1 st lever 78. The 2 nd rod 80 is pivotally supported in the vehicle width direction, and thereby the same operational effects as those of the above embodiment are exhibited.
The slide mechanism 60, which can be attached, fixed, and moved, may be attached to only one lower rail 24 of the pair of left and right lower rails 24. In this case, the other lower rail 24 may be provided with a thin plate-like guide piece or the like that can be inserted into the groove portion 38 of the other lower rail 24 without the slide mechanism 60 being attached, so that the ottoman 10 can be moved (slid) in the front-rear direction.
The footrest and the vehicle seat system with the footrest according to the present invention are not limited to the automobile. For example, any vehicle having a vehicle seat system that moves a vehicle seat along a rail member, such as a large bus or a railway vehicle, can be applied.
