Description

[Technical field]

[0001] The present invention relates to a vehicle seat having a headrest incorporating an electronic device. [Background technology]

[0002] Conventionally, a vehicle seat as described above is described, for example, in Patent Document 1. The vehicle seat described in Patent Document 1 has a configuration in which an electronic device is built into the headrest, and a harness connected to the electronic device is disposed inside the seat back.

[0003] In the process of mounting a vehicle seat on a vehicle body in a vehicle assembly line, depending on the vehicle model, the headrest may hinder smooth loading into the vehicle body. In such a case, in the past, the headrest was removed from the seat back and placed on the seat surface before being loaded into the vehicle body, and then the headrest was attached to the seat back.

[0004] [Patent Document 1] JP 2014-125188 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of a vehicle seat equipped with a headrest incorporating electronic devices, such as the vehicle seat described in Patent Document 1, the harness must also be removed when the headrest is removed. Therefore, with conventional vehicle seats, after the seat is brought into the vehicle body, it is necessary to fix the seat to the vehicle body, attach the headrest, and connect the harness, which makes the assembly work to the vehicle body complicated. It was an issue to solve such a problem.

[0006] The present invention has been made in response to the above-mentioned conventional problems, and aims to provide a vehicle seat equipped with a headrest incorporating electronic equipment, which can hold the headrest well even when removed from the seat back with the harness still connected, and can facilitate assembly work into the vehicle body. [Means for solving the problem]

[0007] The vehicle seat according to the present invention is equipped with a headrest with built-in electronic equipment. The headrest includes a pillar that can be attached to and detached from a mounting hole in the upper part of the seat back, a harness that runs from the electronic equipment through the inside of the pillar to the inside of the seat back, and a retention mechanism that holds the headrest at a predetermined height relative to the seat back when the headrest is removed from the seat back. Effect of the Invention

[0008] The vehicle seat of the present invention, in a vehicle seat equipped with a headrest incorporating electronic equipment, can, with the harness still connected, reduce the load on the harness while maintaining a good hold on the headrest after it has been removed from the seat back, facilitating the subsequent assembly work into the vehicle body.

[Diagram 3] 1A is a cross-sectional view of a main part showing a state in which a headrest has been removed from a seat back, and FIG. 1B is a cross-sectional view of a main part showing a state in which the headrest is attached to the seat back. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] First Embodiment The vehicle seat S shown in Fig. 1 is provided with a detachable headrest R with built-in electronic devices on the upper part of a seat back B. Although not shown in the figure, the electronic devices may be various devices such as speakers and monitors, and are not limited to these.

[0011] In addition, the above-mentioned vehicle seat S is suitable for use in vehicle types in which the headrest R would be an obstacle when mounting the seat on the vehicle body on a vehicle (automobile) assembly line, but it can naturally be applied to other vehicle types as well.

[0012] The headrest R of the vehicle seat S described above includes a pair of left and right pillars 2, 2 that can be attached to and detached from a pair of left and right mounting holes 1, 1 provided in the upper part of the seat back B, and a harness H that runs from an electronic device through the inside of the pillars 2, 2 to the inside of the seat back B. One end of the harness H is connected to the electronic device, and the other end is connected to a power source or other device (not shown). The pillar 2 is shaped like a pipe through which the harness H passes, and the height of the pillar 2 can be adjusted while the pillar 2 is attached to the seat back B by a ratchet mechanism provided between the pillar 2 and the seat back B.

[0013] The vehicle seat S is provided with a retaining mechanism that retains the headrest R, which has been removed from the seat back B, at a predetermined height of the seat back B. The vehicle seat S of this embodiment is provided with a protective sheet 3 that encases at least the seat back B, and the retaining mechanism is a retaining pocket 4 that is integrated with the protective sheet 3 and that accommodates the headrest R.

[0014] In addition, the protective sheet 3 in the illustrated example wraps around the entire vehicle seat S and has a retaining pocket 4 on the front side of the seat back B, but it is also possible to position the retaining pocket 4 on the rear side of the seat back B.

[0015] In the vehicle seat S having the above-mentioned configuration, the headrest R removed from the seat back B is stored in the holding pocket 4 with the harness H still connected. At this time, the holding pocket 4 holds the headrest R while leaving the harness H with a certain degree of slack.

[0016] In this manner, the vehicle seat S is provided with a headrest R incorporating electronic devices, and the retaining pocket 4 as a retaining mechanism can effectively retain the headrest R removed from the seat back B while reducing the load on the harness H.

[0017] As a result, in the assembly process of the vehicle seat S to the vehicle body, after it is transported into the vehicle body, it is sufficient to fix it to the vehicle body and attach the headrest R to the seat back B; since there is no need to connect the harness H, this makes it easier to assemble the seat S to the vehicle body and also contributes to shortening the assembly time, etc.

[0018] <Second embodiment> 2 and 3 are diagrams illustrating a second embodiment of a vehicle seat according to the present invention. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0019] The vehicle seat S shown in Fig. 2 has a retaining mechanism that is flexible and has an elongated retaining member 10 that reaches from the inside of the pillar 2 to the inside of the mounting hole 1 of the seat back B. The material of the retaining member 10 is not limited, but it is made of resin, for example. As shown in Fig. 3, the retaining member 10 has an upper locking portion 10A whose downward movement is restricted by an engaging portion 2A provided at the lower end of the pillar 2, and a lower locking portion 10B at its lower end whose upward movement is restricted by an engaging portion 1A provided at the lower end of the mounting hole 1.

[0020] The upper locking portion 10A of the holding member 10 in the illustrated example has an expanded width. In contrast, the engagement portion 2A of the pillar 2 has a tapered shape with a smaller diameter at the lower end, and functions to prevent the upper locking portion 10A from coming off downward.

[0021] The lower locking portion 10B of the retaining member 10 is formed in a pair of left and right hooks extending obliquely upward. In contrast, the mounting hole 1 in the illustrated example is formed in a support member 11 fixed to the upper part of the seat back B, and the opening at the lower end serves as an engagement portion 1A, which functions to prevent the lower locking portion 10B from coming off in the upward direction.

[0022] As shown in Fig. 3(A), the holding member 10 has a length such that the harness H is arranged along both sides, and the upper locking portion extends outside the mounting hole 1 when the lower locking portion 10B is locked with the engagement portion 1A of the mounting hole 1, and more preferably, the length is shorter than the length of the harness H. This allows the holding member 10 to be freely bent outside the mounting hole 1, as shown by the imaginary line in Fig. 3(A).

[0023] Furthermore, as a more preferred embodiment, the retaining member 10 has a retaining portion 10C in the middle that holds the middle of the harness H, and in the illustrated example, it has two cylindrical retaining portions 10C, 10C at the top and bottom that hold the harness H in a passed-through state.

[0024] 2, the vehicle seat S having the above-mentioned configuration holds the headrest R, which has been removed from the seat back B, in a suspended state by the retaining member 10, with a certain degree of slack in the harness H. At this time, the suspended position of the headrest R is maintained by the engagement between the upper locking portion 10A of the retaining member 10 and the engagement portion 2A of the pillar 2, and the engagement between the lower locking portion 10B of the retaining member 10 and the engagement portion 1A of the mounting hole 1.

[0025] After the vehicle seat S is assembled to the vehicle body, as shown in Fig. 3(B), it is only necessary to insert the pillar 2 of the headrest R into the mounting hole 1. The retaining member 10 is maintained at a predetermined height by engaging with the engaging portion 2A of the pillar 2.

[0026] In this way, the vehicle seat S provided with the headrest R incorporating the electronic device can, by means of the holding member 10 as the holding mechanism, hold the headrest R removed from the seat back B well while reducing the load applied to the harness H with the harness H connected. As a result, in the step of assembling to the vehicle body, the work of carrying in and fixing to the vehicle body can be facilitated, and it can also contribute to shortening the working time and the like.

[0027] Further, since the vehicle seat S adopts the long holding member 10 having a length shorter than that of the harness H, when the headrest R is held, the burden on the harness H can be eliminated, and damage to the harness H and the like can be prevented beforehand.

[0028] Furthermore, since the vehicle seat S adopts the holding member 10 having the holding portion 10C for holding the middle of the harness H, when the headrest R is attached to the seat back B, the holding member 10 functions as a guide for the harness H inserted into the attachment 1, and the assembly work of the headrest R can be performed easily and quickly.

[0029] Note that the vehicle seat S in the illustrated example is configured to include the harness H and the holding member 10 in each pillar 2, but a configuration in which the harness H is passed through only one of the pillars 2 may be employed. In this case, by providing the holding member 10 on both pillars 2, the posture of the suspended headrest R can be stabilized.

[0030] The details of the configuration of the vehicle seat according to the present invention are not limited to only the above-described embodiments, and can be appropriately changed without departing from the gist of the present invention.
