Vehicle seat

Abstract

A seat cushion for a vehicle, which includes one seat cushion portion and another seat cushion portion, such that one or both of those one and another seat cushion portions may be displaced via side rails. A storage space is defined in a forwardly-facing region of one of those two seat cushion portions. An opening region is provided to that storage space and constitutes an ingress/egress opening of the storage space for allowing an article(s) to be entered thereinto and taken out therefrom. This opening region is defined in a lateral surface of a selected one of the two seat cushion portions. Thus, when the selected one of the two seat cushion portions is displaced in a forward direction to protrude from the other of the two seat cushion portions, the lateral surface is exposed outwardly on a side facing a center of the vehicle.

MODE FOR CARRYING OUT THE INVENTION

(6) Hereinafter, with reference to the annexed drawings, a detailed description will be made of preferred embodiments of a vehicle seat in accordance with the present invention.

(7) In FIGS. 1 and 2, a vehicle seat 1 is depicted to be a second rear seat comprising: a first split-type seat portion 1A (on the left side in the Figures) composed of a wide seat section and a narrow seat section, such that a ratio between the wide seat section and the narrow seat section is 6:4 as viewed in a transverse direction of the vehicle seat; and a second seat portion 1B (on the right side in the Figures). Those first and second seat portions are arranged to be displaceable by means of slide rails 2, 2, 2 and 2, such that one of the first and second seat portions may be moved forwardly and positioned ahead of the other of the first and second seat sections, while on the other hand, both of the first and second seat portions may be moved and positioned forwardly from their respective home positions. In this regard, the first seat portion 1A includes a subsidiary seat area defined integral therewith, such subsidiary seat area constituting a middle seat portion 1C adjacent to the second seat position 1B. The first seat portion 1A comprises a left-side seat cushion SC1 and a left-side seat back SB1. The second seat portion 1B comprises a right-side seat cushion SC2 and a right-side seat back SB2. The middle seat portion 1C comprises a middle seat cushion SC3 and a middle seat back SB3.

(8) In other words, the seat cushions SC1 and SC3 of the first seat portion 1A and the seat cushion SC2 of the second seat portion 1B are respectively movable on and along the associated lower rails 2, 2, 2 and 2 of the slide rails fixed on a vehicle floor FL, such that one of the seat cushions SC1 and SC2 may be moved forwardly and positioned ahead of the other of the seat cushions SC1 and SC2, while both of the seat cushions SC1 and SC2 be moved and positioned forwardly from their respective home positions. Connected respectively to those two seat cushions SC1 and SC2 are the seat backs SB1 and SB2 each being inclinable and foldable down.

(9) Also, the middle seat cushion SC3 of the middle seat portion 1C forming a part of the first seat portion 1A are provided with corresponding lower rails 2 of the slide rails fixed on the vehicle floor.

(10) As shown in FIGS. 3 and 4, a box-like container 4 formed of a synthetic resin or metallic material, which has a robust property sufficient to retain its original shape, is provided in the middle seat cushion SC3 of the middle seat portion 1C, such that the container 4 is located near to a front end of that middle seat cushion which faces a forward side of the seat. Defined in that box-like container 4 is a storage space S adaptable for use as a storage region in which an article(s), such as a small article(s) or a tissue paper box B, may be contained and stored. The seat cushion SC3 has a rectangular ingress/egress opening 6 defined in a lateral surface 5 thereof, wherein the lateral surface 5 faces a center of a vehicle in which the seat is to be provided. The box-like container 4 is formed such that its right end is closed, while its left end is opened to define an opening region 4a. This opening region 4a of the box-like container is indicated as being positioned within the ingress/egress opening 6 of the seat cushion SC3 and accessible therethrough. Accordingly, a small article(s) or a tissue paper box B for instance can be entered inserted into the ingress/egress opening 6 along a lateral direction of the seat cushion towards the box-like container.

(11) The box-like container 4 has a rear surface facing a rear side of the seat cushion. Provided to that rear surface of the box-like container is a securing hook member 4c so configured to be hookingly attached about a tubular frame F which is provided in the seat cushion SC3 at a forwardly-facing end region of the same SC3. As shown, the securing hook member 4c is attached about the tubular frame F disposed at the forwardly-facing end region of the seat cushion and is fixedly secured to that tubular frame as by welding or securing screw (s). In that manner, the box-like container 4, having a robust property sufficient to retain its original shape, is fixed to the tubular frame F in the seat cushion SC3. This means that such box-like container 4 can easily be built in the seat cushion SC3 and stably retained therein, with a great reliability.

(12) Also, the box-like container 4 is shown to be situated within a cut-out portion of a foam padding PB provided in the seat cushion SC3. The foam padding PB is supported on a support element F1. Fixed to that support element F1 is an upper rail 20 slidably engaged with the lower rail 2 of the seat rail. A trim cover assembly 7, which forms a surface cover element of the seat cushion SC3, includes a trim cover section 7a adapted to cover the box-like container, and therefore, the box-like container 4 is covered with such trim cover section 7a. A lower end portion 7aE of the trim cover section 7a is fixedly secured to a bottom surface 4d of the box-like container 4 by an adhesive. With this arrangement, the box-like container 4 is invisibly provided in the seat cushion SC.

(13) A slit 8 is formed in a forwardly-facing area of the trim cover section 7a corresponding to a front surface 10 of the seat cushion SC3, in such a fashion that the slit 8 communicates with the storage space S defined in the box-like container 4. The slit 8 is shown to be elongated horizontally and is substantially identical in size to a slit 4b formed in a front surface of the box-like container 4, wherein such front surface of the box-like container faces the front side of the seat cushion. Hence, a user can pull out a tissue paper 9 from the tissue paper box B placed in the box-like container 4, so that the tissue paper may be moved through and past both two slits 4b and 8 in a direction from the inside of the box-like container to the outside thereof, and drawn out from the front side of the seat cushion SC3.

(14) The foregoing arrangement of the slit 8 enables a user to pull out the tissue paper 9 one by one from the tissue paper box B placed in the storage space S. Accordingly, the above-described disposition of the tissue paper box B is obviously within reach of a user and offers a great convenience to him or her, which is a good solution to the problem that the user is quite often annoyingly forced to find an appropriate place on which the tissue paper box can be put, in the vehicle.

(15) Also, according to the present vehicle seat, the storage space S is disposed in the forwardly-facing end region of the seat cushion SC3 of the middle seat portion 1C, and such forwardly-facing end region of the seat cushion SC3 is a location to receive a relatively small weight of a passenger. Namely, the passenger's body portion may hardly reach the storage space S, and therefore in most cases, the passenger will not feel any objectionable seating touch on the seat cushion SC3. In addition, the storage space S can be formed to a large size, thereby permitting increase of its dimensions for storage of articles therein.

(16) Further, for example, when it is desired to store the tissue paper box B in the storage space S, the first seat portion 1A may be moved forwardly relative to the second seat portion 1B, as shown in FIG. 3, so that the former 1A is positioned ahead of the latter 1B. In that instance, the lateral surface 5 of the seat cushion SC3 of the middle seat portion 1C forming a part of the first seat portion 1A is exposed to the outside, wherein that lateral surface 5 faces a center of a vehicle in which the seat is to be provided. Such exposure of the lateral surface 5 therefore makes accessible the opening region 4a that forms a part of the ingress/egress opening 6 of the storage space S, whereby for example a user can easily place the tissue paper box B in the storage space S and also can easily take out the tissue paper box B from the storage space S.

(17) Furthermore, the first seat portion 1A that has been moved forwardly as stated above may be moved back to a rearward normal position shown in FIG. 1, so that the seat cushion of the first seat portion 1A will be positioned abreast of the seat cushion SC2 of the second seat portion 1B in aligned relation therewith. Or, that first seat portion 1A may be moved rearwardly relative to the second seat portion 1B and positioned rearward of the seat cushion SC2. In either way, the lateral surface 5 of the seat cushion SC3 of the middle seat portion 1C forming a part of the first seat portion 1A will disappear behind the seat cushion SC2 of the second seat portion 1B, so that the opening region 4a of the storage space S of the seat cushion SC3 can be concealed and invisible. This is quite advantageous for maintaining the appearance of the seat 1 in an aesthetically desirable condition.

(18) As shown, an entirety of the seat cushion includes the aforementioned 6:4 split seat cushion and the central area corresponding to the middle seat cushion, and particularly where where such seat cushion arrangement is applied to a second or third rear seat, the said central area of the seat cushion is rarely used by a seat occupant (s), so that there is almost no chance for the seat occupant's body portion to reach the storage space S, and therefore in most cases, the seat occupant will not feel any objectionable seating touch on the seat cushion. In addition, by simply setting the left- and right-side seat cushions abreast of each other, the ingress/egress opening 6 can be concealed therebetween and invisible, whereas on the other hand, to move one of those two seat cushions forwardly to protrude from the other thereof will cause the ingress/egress opening 6 to appear outwards. This arrangement can effectively prevent the aesthetic appearance of the seat 1 from being undesirably degraded.

(19) It should be understood that the present invention is not limited to the above-described embodiment.

(20) As suggested in FIG. 5 for example, a storage space Sd may be defined in the foam padding PB forming a part of the seat cushion SC by cutting out a localized region of the foam padding, such that the storage space is given in a hollow fashion. In other words, the foam padding PB may be cut out so as to define a hollow therein, whereby the storage space Sd is given at the hollow in the foam padding, and further, a slit PB1 may be so formed as to penetrate the front region at 10 of the seat cushion SC3 towards the storage space Sd, so that the slit PB1 communicates with the storage space Sd in which the tissue paper box 4 is placed. Such slit PB1, which extends horizontally, is shown to be in alignment with a slit 81 which is formed in a surface cover element 7 on a side facing the front side of the storage space Sd. According to this embodiment, the storage space Sd can be easily and readily formed in the seat cushion SC, with an extremely simplified configuration of the storage space itself.

(21) Designation 7e denotes an end of the surface cover element 7. This end of the surface cover element is securely connected to a distal end F1E of the support member F1 provided to the foam padding PB.

(22) The above-described vehicle seat may be used as a front or first seat, a second rear seat, or third rear seat.

(23) It is to be noted that the storage space S may be formed in one or both of the seat cushions SC2 and SC3 respectively of the first and second seat portions. In addition, the storage space S of the box-like container 4 be so modified to allow storage of an umbrella(s) therein, for instance. In that mode, since there is quite a little occasion for a user to put the umbrella or other article that does not require its frequent use in such kind of storage space and take it therefrom, there may be eliminated the necessity of forming the aforesaid slit 8 in the front surface 10 of the seat cushion SC.

(24) Moreover, a lid element may be provided to permit opening and closing of the ingress/egress opening 6, in which case, an upper end of the lid element may be sewn with the surface cover element 7 adjacent to that opening 6. Preferably, this lid element be releasably secured to the surface cover element 7 for the opening and closing purposes, as by a zipper fastener, a Velcro loop-and-hook fastener, or a magnetic securing device.
