Summary of the Invention

Problems to be Solved by the Invention

[0004] In a vehicle, when people are seated on both of the above two seats, the shoulders of both seated persons may contact each other. Therefore, if the contact state between the shoulders of both seated persons continues during the movement of the vehicle, the comfort of both seated persons will be impaired. Also, in a vehicle, it is often difficult to move the seat.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle seat capable of improving the comfort of the seated person.

Means for Solving the Problems

[0006] The present invention has been made to solve at least part of the above problems, and can be realized as the following aspects or application examples.

[0007] The vehicle seat according to this application example is a vehicle seat that is positioned adjacent to another seat on the side of that seat, in the same orientation as that other seat, and comprises a seat plate portion that supports the buttocks of the occupant, and a backrest portion connected to the seat plate portion that supports the back of the occupant, wherein the back support surface of the backrest portion that contacts the back of the occupant is located on the front side than the backrest portion of the other seat.

[0008] In the vehicle seat described in this application example, the shoulders of the person sitting in the vehicle seat are positioned more directly in front of the shoulders of the person sitting in the other seat. Therefore, even if a person with shoulders wider than the width of each seat is seated in both the vehicle seat and the other seat, contact between the shoulders of the person sitting in the vehicle seat and the shoulders of the person sitting in the other seat is avoided. Thus, the vehicle seat can improve the comfort of the person sitting in the vehicle seat. [Brief explanation of the drawing]

[Figure 6] This is a schematic top view showing the configuration of the first and second seats in the open position of a modified example. [Modes for carrying out the invention]

[0010] Figure 1 is a schematic front view showing the configuration of the vehicle 10 and seats 14 of this embodiment. The vehicle 10 is, for example, a truck or other vehicle. Inside the vehicle 10, in addition to the driver's seat 12, there are multiple seats 14 which are seats for the vehicle. The multiple seats 14 include a first seat 14a and a second seat 14b (another seat relative to the first seat 14a). In the following description, the first seat 14a may be simply referred to as seat 14a, and the second seat 14b may be simply referred to as seat 14b.

[0011] The fronts of the first seat 14a and the second seat 14b face the same direction. Specifically, the fronts of the first seat 14a and the second seat 14b face the front of the vehicle 10. In addition, the first seat 14a is positioned next to the second seat 14b on its side, facing the same direction as the second seat 14b.

[0012] The first seat 14a includes a seat plate 20a, a backrest 30a, and an opening / closing mechanism 40a, etc., and the second seat 14b includes a seat plate 20b, a backrest 30b, and an opening / closing mechanism 40b, etc.

[0013] The seat plates 20a and 20b are plate-shaped and support the seated person's buttocks. The surfaces of the seat plates 20a and 20b that contact the seated person's buttocks are the seat surfaces 22a and 22b. The backrests 30a and 30b are plate-shaped and support the seated person's back. The surfaces of the backrests 30a and 30b that contact the seated person's back are the back support surfaces 32a and 32b. The surfaces of the backrests 30a and 30b opposite to the back support surfaces 32a and 32b are the back surfaces 34a and 34b (see Figure 2).

[0014] The backrests 30a and 30b are connected to the seat plates 20a and 20b via opening and closing mechanisms 40a and 40b, and the backrests 30a and 30b are capable of tilting as appropriate around pivot axes 16a and 16b. The opening and closing mechanisms 40a and 40b are, for example, hinges with a locking function.

[0015] Seats 14a and 14b can be switched from one of the closed state and the open state to the other state by tilting (opening and closing) the backrest parts 30a and 30b. Regarding seats 14a and 14b, the open state refers to a state in which the entire seats 14a and 14b form a substantially L shape in side view when the backrest parts 30a and 30b open, and it is possible to support the seated person. On the other hand, the closed state refers to a state in which the seating surfaces 22a and 22b of the seat plate parts 20a and 20b are in contact with the back support surfaces 32a and 32b of the backrest parts 30a and 30b when the backrest parts 30a and 30b close.

[0016] Also, when seats 14a and 14b are in the closed state or the open state, the current state of seats 14a and 14b is maintained by the locking function of the opening and closing mechanisms 40a and 40b. When the opening and closing mechanisms 40a and 40b receive an unlocking operation, the backrest parts 30a and 30b can be tilted.

[0017] FIG. 2 is a schematic side view showing the configuration of the first seat 14a and the second seat 14b in the open state of the present embodiment. Note that the first seat 14a and the second seat 14b are arranged adjacent to each other with their side faces facing each other as described above. However, in FIG. 2, the first seat 14a and the second seat 14b are shown shifted from each other in order to clarify the difference in configuration between the first seat 14a and the second seat 14b.

[0018] The backrest part 30a of the first seat 14a is thicker by a thickness T1 on the closing direction side than the backrest part 30b of the second seat 14b. When the first seat 14a and the second seat 14b are in the same state (closed state or open state), the back support surface 32a of the first seat 14a is located on the closing direction side by a thickness T1 from the back support surface 32b of the second seat 14b.

[0019] Also, only when both the first seat 14a and the second seat 14b are in the open state, it can be said that the backrest part 30a of the first seat 14a is thicker by a thickness T1 on the front side than the backrest part 30b of the second seat 14b, and the back support surface 32a of the first seat 14a is located on the front side by a thickness T1 from the back support surface 32b of the second seat 14b.

[0020] The seat board portion 20a of the first seat 14a is thinner by the thickness T2 than the seat board portion 20b of the second seat 14b, and the position of the seat surface 22a of the first seat 14a is lower by the thickness T2 than the position of the seat surface 22b of the second seat 14b. Note that the thickness T1 and the thickness T2 are the same values.

[0021] FIG. 3 is a schematic top view showing the configurations of the first seat 14a and the second seat 14b in the open state of the present embodiment. As described above, when the first seat 14a and the second seat 14b are in the open state, the back support surface 32a of the first seat 14a is positioned on the front side by the thickness T1 than the back support surface 32b of the second seat 14b. Therefore, as shown in FIG. 3, when a person is seated on both the first seat 14a and the second seat 14b, the shoulder of the person seated on the first seat 14a is positioned on the front side by the thickness T1 than the shoulder of the person seated on the second seat 14b.

[0022] That is, according to the first seat 14a, even when a person with a shoulder width wider than the seat widths of the first seat 14a and the second seat 14b is seated on both the first seat 14a and the second seat 14b, it is possible to avoid the shoulders of the person seated on the first seat 14a and the person seated on the second seat 14b from contacting each other. Therefore, according to the first seat 14a, the comfort of the person seated on the first seat 14a and the person seated on the second seat 14b is improved.

[0023] [[ID=ll]] Also, in the present embodiment, as described above, the position of the seat surface 22a of the first seat 14a is lower by the thickness T2 than the position of the seat surface 22b of the second seat 14b. Therefore, according to the first seat 14a, the center of gravity position of the person seated on the first seat 14a is made lower than the center of gravity position of the person seated on the second seat 14b, and as a result, the stability of the person seated on the first seat 14a is improved.

[0024] Also, if the position of the seat surface 22a of the first seat 14a is lower by the thickness T2 than the position of the seat surface 22b of the second seat 14b, as shown in FIG. 3, when a person is seated on both the first seat 14a and the second seat 14b, the position of the thigh of the person seated on the first seat 14a is lower by the thickness T2 than the position of the thigh of the person seated on the second seat 14b.

[0025] In other words, with the first seat 14a, even when people are seated in both the first seat 14a and the second seat 14b, contact between the thighs of the person seated in the first seat 14a and the thighs of the person seated in the second seat 14b is avoided. Therefore, with the first seat 14a, the comfort of the person seated in the first seat 14a and the person seated in the second seat 14b is further improved.

[0026] Figure 4 is a schematic side view showing the configuration of the first seat 14a and the second seat 14b in the closed state of this embodiment. As described above, the first seat 14a and the second seat 14b are arranged adjacent to each other with their sides facing each other. However, in order to clarify the difference in configuration between the first seat 14a and the second seat 14b, Figure 4 shows the first seat 14a and the second seat 14b offset from each other.

[0027] Furthermore, in this embodiment, as described above, the backrest portion 30a of the first seat 14a is thicker by T1 than the backrest portion 30b of the second seat 14b, and the seat plate portion 20a of the first seat 14a is thinner by T2 than the seat plate portion 20b of the second seat 14b. Moreover, thickness T1 and thickness T2 are the same value. Therefore, in this embodiment, the sum of the thickness of the seat plate portion 20a and the thickness of the backrest portion 30a in the first seat 14a is the same as the sum of the thickness of the seat plate portion 20b and the thickness of the backrest portion 30b in the second seat 14b.

[0028] Therefore, when both the first seat 14a and the second seat 14b are closed, the back surfaces 34a of the first seat 14a and 34b of the second seat 14b are at similar heights and are substantially flush. With such a first seat 14a, when both the first seat 14a and the second seat 14b are closed, the back surfaces 34a of the first seat 14a and 34b of the second seat 14b can be used as a single mounting surface, improving convenience.

[0029] This concludes the description of this embodiment. However, the specific configuration shown in this embodiment is merely an example, and the embodiments of the present invention are not limited to the configuration shown in this embodiment.

[0030] Figure 5 is a schematic side view showing the configuration of the first seat 14a and the second seat 14b in the open state of a modified example. As described above, the first seat 14a and the second seat 14b are arranged adjacent to each other with their sides facing each other. However, in order to clarify the difference in configuration between the first seat 14a and the second seat 14b, the first seat 14a and the second seat 14b are shown offset in Figure 5. Figure 6 is a schematic top view showing the configuration of the first seat 14a and the second seat 14b in the open state of a modified example. As shown in Figures 5 and 6, the backrest portion 30a of the first seat 14a may be pre-positioned on the front side of the backrest portion 30b of the second seat 14b, so that when both the first seat 14a and the second seat 14b are in the open state, the back support surface 32a of the first seat 14a is located on the front side of the back support surface 32b of the second seat 14b. Furthermore, such modifications may be combined with the above-described embodiments.

[0031] Furthermore, the configuration that positions the back support surface 32a of the first seat 14a further forward than the back support surface 32b of the second seat 14b when both the first seat 14a and the second seat 14b are open can also be applied to vehicle seats that do not have an opening and closing function. Similarly, the configuration that lowers the position of the seat surface 22a of the first seat 14a than the position of the seat surface 22b of the second seat 14b can also be applied to vehicle seats that do not have an opening and closing function.

[0032] Furthermore, although the above embodiment uses a truck as the vehicle 10, the configuration of the first seat 14a can also be applied to seats in vehicles such as ships and airplanes. In addition, the configuration of the first seat 14a can also be applied to seats in facilities such as hospitals, schools, and government offices. [Explanation of symbols]
