Patent Application
20200108745
This disclosure relates to a vehicle seat, for example, this disclosure can be applied to a vehicle seat utilizing the back for loading space.
For the vehicle seat, the one having structure that a seat back is pushed down forward and the back of the seat back is utilized for loading space can be given (for example, JP-A No. 2013-116661).
Concave clearance is formed between the back directed upward and a floor surface on the back side (for example, a floor surface of cargo room) by pushing down the seat back forward.
An object of this disclosure is to provide a vehicle seat covering the concave clearance.
Another object and a new characteristic will be clarified from description of this disclosure and accompanied drawings.
Brief description of a summary of representatives in this disclosure is as follows.
That is, the vehicle seat is provided with a seat cushion, a seat back connected to the seat cushion and turnable in a longitudinal direction, and a plate member attached to the back of the seat back. The plate member is configured by a core plate and a cover that covers the core plate, the plate member is sewed together with a cover of the back of the seat back, and a sewed part of the cover of the plate member and the cover of the seat back functions as a turning axis of the plate member. The plate member is pushed on the back side by pushing down the seat back forward, the plate member is turned an unfolded state covering concave clearance formed between the back directed upward of the seat back and a floor surface on the back side, the plate member is raised forward by raising the seat back backward, and the plate member is turned a housed state in which the plate member is piled on the back of the seat back.
An embodiment will be described referring the drawings below. However, the same reference numeral is allocated to the same component in the following description and its repeated description may be omitted. The drawings may be schematically expressed as to width, thickness and a configuration of each part, compared with an actual situation so as to more clarify description, however, to the end, the drawings are one example, and the drawings do not limit interpretation of the present invention.
The following description is based upon a case that a vehicle equipped with a vehicle seat is placed on a horizontal plane and a vertical direction is defined as a perpendicular direction. In addition, a longitudinal direction (FR, RR) is defined so that it coincides with a longitudinal direction of the vehicle and a lateral direction (a direction of width) is defined so that it coincides with a direction of the width of the vehicle. FR denotes a forward direction of the vehicle and RR denotes a backward direction of the vehicle. Moreover, the right side and the left side respectively viewed from the back of the vehicle of the vehicle seat are called RH and LH in the following description.
First, referring to
As shown in
As shown in
The seat cushion 22 includes a seat cushion frame, a urethane pad and a cover. The seat backs 24, 26 also have the similar configuration and are configured by a urethane pad fixed to the seat back frame and wrapped by a cover 24b.
The plate member 30 is in the shape of a flat plate having the similar lateral width to lateral width of the seat back 24 as shown in
A configuration and size of the plate member 30 are formed in accordance with vehicle structure such as the level difference part 2a, the wall or its opening 3b. In a state in which the seat back 24 stands, the plate member 30 is fixed by the level difference part 2a to prevent the seat back from being pushed down backward. In other words, in the state in which the seat back 24 stands, a part of the plate member 30 is held between the seat back 24 and the level difference part 2a. As shown in
The back row seat 14 has a configuration that the seat back 24 is pushed down forward and its back can be turned at an approximately same level as a top face of the floor 3a as shown in
As shown in
Hereby, the plate member has a foldable/unfoldable configuration that as shown in
Next, the details of the plate member 30 will be described referring to
As shown in
In
Thickness of the plate member 30 in the vicinity of the seams 24c is equivalent to thickness of the cover 30b and the thickness of the plate member between the seams 30c to the seams 30d is equivalent to the whole thickness of one layer of the plastic plate 30a and three layers of covers 30b. The plate member 30 is pushed down backward using the seams 24c for the turning axis, however, as the plate member in the vicinity of the seams 24c is thin, turning is easily performed. In addition, in a state in which the seat back 24 is pushed down forward, the vicinity of the seams 30c is located on the back side of the seat back 24, the vicinity of the seams 30d is located on the side of the floor 3a, a top face of the plate member 30 is protruded from the back of the seat back 24 and the top face of the floor 3a by the thickness of the plate member 30, however, as no hinge bracket is used, a large flat surface formed by the back of the seat back 24, the plate member 30 and the floor 3a can be utilized for a cargo room surface without providing a recess on the back of the seat back 24 and the floor 3a.
The present invention made by these inventors has been described in the concrete on the basis of the embodiment, however, the present invention is not limited to the above-mentioned embodiment, and it need scarcely be said that the present invention is variously variable.
For example, in the embodiment, the vehicle is provided with two rows of seats, however, the vehicle may be also provided with more rows of seats than two rows of seats. In this case, the back row seat in the embodiment is applied to the backmost seat.
Moreover, in the embodiment, the seat back of the back row seat is divided in two; however, the back row seat may be also configured by one seat back.
