Description

[Detailed description of the invention] The present invention relates to a car seat, and more specifically, it is a rear seat in a type of car such as a wagon that has a combined living space and luggage space, and is designed to be used in the luggage compartment with an extremely simple operation. This invention relates to an automobile seat configured to be used as a bed that is in close contact with the floor surface of an automobile.

A conventional example of a car seat configured so that it can also be used as a bed is a so-called full reclining seat described in, for example, Japanese Utility Model Application Publication No. 57-101633. In this fully reclining seat, the seat back can be tilted back until it is approximately at the same height as the seat cushion, and the seat cushion and seat back can be used as a series of approximately horizontal bed surfaces. However, in the case of such a fully reclining seat, the seat back hinge must be strengthened to support the load applied to the seat back when fully reclining, and the seat back must have a strong frame, which is extremely inconvenient in terms of weight and cost. In addition, when additional auxiliary mats are added to increase the bed length, there are also drawbacks such as the need to support the auxiliary mats in a complicated manner.
Furthermore, since the bed surface is formed at a high position quite far from the floor surface, the ceiling approaches the occupant's eyes when lying on the bed surface, making it difficult to feel mentally stable.

The present invention was devised in view of the above-mentioned circumstances, and provides an automobile seat configured so that it can be quickly converted into a long bed that is in close contact with the automobile floor surface through easy operation. The purpose is to

That is, in the automobile seat according to the present invention, the front leg to be attached to the front part of the seat cushion is pivotally connected to the seat cushion so that its upper end can be locked in an upright state, and its lower end is attached to the automobile floor. At the same time, the rear leg to be attached to the rear of the seat cushion is pivotally mounted at its upper end to be able to stand up and fold with respect to the seat cushion, and the seat back is fully pivoted to the seat cushion. It is characterized by being installed so that it can be reclined.

Thus, by folding the rear legs and unlocking the front legs, the seat cushion can be moved until it comes close to the floor surface while maintaining a substantially horizontal state, and the seat back can be fully reclined in this state. In this case, the seat cushion and the seat bag form a bed surface that is substantially close to the floor surface.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The drawings show an example in which the present invention is applied to the rear seat of a truck vehicle called a one-box car.

Reference numeral 1 denotes a front seat, which is installed above the engine E, and there are usually a pair of seats for one person on the left and right. 2 is the rear seat, which is usually a so-called bench seat that seats two or three people. The front legs 3 of this rear seat 2 are rotatably supported with respect to the floor surface 4, and the luggage space 5 can be expanded by tilting forward around this support part. Normal. The seat cushion 6 and the seat back 7 constituting the rear seat 2 are hinged to each other. It has a full reclining structure that allows the seats to be folded down in a stacked manner, and also to be folded back in a substantially horizontal direction that is continuous with the seat cushion. In the present invention, the front legs 3 of the rear seat 2 have an upper end 3a pivotally connected to the seat cushion 6 in a lockable manner in an upright state, and a lower end 3b rotatably supported with respect to the floor 4. Moreover, the rear leg 8 is pivotally connected to the seat cushion 6 at its upper end 8a so as to be able to stand up and fold down. Further, in this embodiment, a bed 9 for expanding the bed surface is attached to the seat bag 7 so that it can be folded.

The details of the structure of the front leg 3, rear leg 8, and bed cushion 9 are shown in FIG.

The upper end portion 3a of the front leg 3 is rotatably supported in the front-rear direction by using a support pin 12 on a support member 11 appropriately provided at the front portion of the frame 10 of the seat cushion 6. The front leg 3 rotates around the support pin 12, but its rotation is restricted by the stopper pin 13, and the lock mechanism 14 maintains the upright position shown by the solid line in FIG. The locking mechanism 14 includes, for example, when the front leg 3 rotates about the support pin 12 from the folded state shown by the chain line in FIG. 2 to the upright state shown by the solid line in FIG. It is preferable to attach an engaging member 16 to a predetermined portion of the front leg 3 so as to lock the reverse rotation of the front leg 3 by engaging with the front leg 3. To unlock the lock mechanism 14, the engagement member 16 may be manually operated to disengage the claw portion 15 and the stopper pin 13. On the other hand, front leg 3
The lower end 3b is rotatably supported by a pivot pin 17 fixed to the floor 4.

The rear leg 8 is supported at its upper end 8a by a support pin 18 provided at the rear of the frame 10 of the seat cushion 6 so as to be rotatable in the front-rear direction. When the rear legs are in the upright state shown by the solid line in FIG. 2, the rear side surface 8c of the upper end of the rear legs 8 comes into contact with an appropriate portion of the frame 10, so that its rotation is restricted. Note that the rear legs are designed to maintain their rotational positions in both the folded state and the upright state by appropriate means such as a spring over the fulcrum. The lower end 8 of this rear leg 8
A cushion rubber 19 is attached to b to prevent the generation of noise between the lower end portion 8b and the floor surface 4.

The bed cushion 9 is made by joining two bed cushions, that is, a first cushion 21 and a second cushion 22, through a flexible material such as a strong cloth 23 so that they can be folded into an overlapping shape. In addition, the upper end 21a of the first cushion 21 is fixed to a rib 24 installed laterally on the back surface of the seat bag 7 through a flexible material such as a strong cloth 25. . Note that the length of the cloth 25 is determined so that the rib 24 to which the cloth 25 is attached is at the upper end 2 of the seat bag 7.
6 and the upper end 21a of the first cushion 21, and the second
If the length of the cushion 22 is set shorter than the length of the first cushion 21 by a distance corresponding to the distance between the upper end 26 and the upper end 21a, as shown in FIG.
a seat back 7 that is slightly inclined backwards, and first and second cushions 21 located on the back side of the seat back 7;
22, each of the upper end portions 26, 21, 22a of the baggage space 5 can be positioned on a vertical plane.
can be used effectively in the same space as before. In addition, in order to fix the bed cushion 9 in a folded state on the back surface of the seat back 7, both ends 27a of the band 27 attached to the back surface of the second cushion 22 are used.
may be secured to the side surface of the seat bag 7 using a securing means 28 such as a hook, hook, or surface fastener.

For example, the rear seat for an automobile constructed as described above can be easily converted into a bed by operating as follows.

First, the band 27 that fixes the bed cushion 9 is released, the rear legs 8 are rotated forward and folded, and then the lock mechanism 14 of the front legs 3 is released and the front legs 3 are folded forward to complete the seat. Move the seat back 7 as shown by the dashed line in FIG. 2 to ground it on the floor 4, then fully recline the seat back 7 backwards as shown by the dashed line in FIG. 2, and move the first and second cushions as shown in FIG. 3. Stretch it horizontally on the floor 4.

Conversely, to change from the bed to the seat, for example, after raising the seat back 7, pull up the entire seat rearward and upward, raise and lock the front legs 3, and also raise the rear legs 8, and then lift the seat back upright. The first and second cushions 21 and 22 may be folded and fixed to the back of the seat bag 7 using the band 27.

Further, the automobile seat according to the present invention can be used as a generally horizontal bed as shown in FIG. 3, and can also be used in various ways, such as by cooperating with the front seat 1.

That is, as shown in FIG.
The front and rear legs 3 and 8 of the front seat 1 are left upright for use as a normal seat, and the seat cushions 6 of the front seat 1 and rear seat 2 are removed by removing the headrest 29 of the front seat 1 and fully reclining it. is a series of substantially horizontal planes having a constant height, the seat back 7 of the rear seat 2 is reclined until its upper end 26 touches the floor 4, and the first and second cushions 21,
22 on the floor surface 4, not only the area behind the rear seat but also almost the entire length of the interior space can be converted into a bed surface.

Furthermore, the rear legs 8 of the rear seat 2 shown in FIG. 4 may be folded up as shown in FIG. 5 according to preference.

Furthermore, as shown in FIG. 6, if the headrest 29 is configured to be inserted into the front part of the seat cushion 6 of the rear seat which has been modified to be approximately horizontal in the same way as in FIG. will be further extended.

As explained above, the automobile seat according to the present invention is moved such that both the front legs 3 and the rear legs 8 at the bottom of the seat cushion 6 are folded and the seat cushion 6 is brought into contact with the floor surface 4. With,
Since the seat back can be fully reclined, it is possible to change from the seat to a long bed that is in close contact with the floor and on which the occupant can lie their whole body, and from the bed to the seat, with an extremely simple operation. . As described above, the bed of the present invention is formed almost closely on the floor surface, so that the load can be directly received by the floor surface, and no special reinforcing structure is required.

In addition, since the bed surface is located close to the floor surface, the effective interior space is widened, and the ceiling approaches the eyes of the occupants lying on the bed, which hinders their sense of mental stability. Such inconveniences will not occur.
