JP5326542B2 - Seat with warning light - Google Patents

Description

  The present invention relates to a seat with a warning light that blinks in conjunction with the lighting of a hazard lamp. Furthermore, the present invention relates to a warning light-equipped sheet that can be used as a warning light such as a hazard lamp by causing the sheet to emit light even if the sheet has the same design as the conventional one. The seat with the warning light is used for a seat of a passenger car or the like.

  Vehicles such as automobiles have a so-called hazard lamp function that simultaneously turns turn signals, which are direction indicators. This turn signal is usually provided at a position where blinking can be seen from anywhere around the vehicle, but it is desired to increase the number of blinking points so that the turn signal can be understood more easily. On the other hand, use of the seat in the vehicle as a warning lamp for a hazard lamp has not been studied.

  On the other hand, an in-vehicle illumination device that emits light on the lower side of a seat base when a vehicle door is opened has been proposed (see Patent Document 1). It has also been proposed to emit light on the back surface of the seat. For example, Patent Document 2 proposes a vehicle seat device that emits light from the back of a net-like backrest provided on the backrest surface of the seat.

However, it is difficult to see whether or not the light emission on the lower side of the seat base shown in Patent Document 1 is emitted from outside the vehicle. Further, when the back surface of the seat is caused to emit light, conventionally, as exemplified in Patent Document 2, since a light source provided in the seat requires a gap and a window lamp to emit light from the seat, a conventional seat is required. The design cannot be left as it is, and it was necessary to make a design with many gaps in advance. The seat with such a design has a problem that the seating comfort is different from that of a normal seat.
This invention is made | formed in view of the said present condition, and it aims at providing the sheet | seat with a warning light which can blink in conjunction with lighting of a hazard lamp. It is another object of the present invention to provide a warning light-attached sheet that can be used as a warning light such as a hazard lamp by emitting light even if the sheet has the same design as the conventional one.

The present invention is as follows.
1. A seat body having a light emitting means on at least a backrest and / or a headrest; and a blinking control means for causing the light emitting means to emit light in conjunction with lighting of a hazard lamp. The light emitting means emits light from the light source. ; and a light guide means for light leakage from transmission to and side light is, the light guide means is a back side of the surface material of the sheet body is provided and along the back side of the stitch of the table surface member, wherein A sheet with a warning light, wherein light leaking from the light guide means leaks from the seam to the outside of the sheet.
2. A seat body having light emitting means on at least a backrest and / or a headrest, and blinking control means for causing the light emitting means to emit light in conjunction with lighting of a hazard lamp, the light emitting means comprising a light source, the seat is a rear side of the surface material of the body, and provided along the back side of the stitch of the table surface member, a warning light sheet with the light emitted from the light source is equal to or leaked from the seam to the seat outside.
3. The light emitting means is provided on the headrest of the seat body. Or 2. Seat with warning light as described.

According to the seat with the warning light, the light emitting means is provided at least at the back and / or above the position, and the flashing light is emitted in conjunction with the hazard lamp as the warning light, so that the visibility as the hazard lamp is further improved. be able to.
Further, when the light emitting means includes a light source and a light guiding means, and the light guiding means is provided on the back side of the seam of the surface material of the sheet body, it is not a substitute for the conventional sheet when the light emitting means is not emitting light. Since it can be provided with a beautiful appearance, a person sitting on the light emitting means is not conscious of the light emitting means, and there is unexpectedness at the time of light emission, and the light leaking from the seam can be a sheet with a warning light that is excellent in beautiful appearance. . In addition, a light source can be provided at an arbitrary place while the light guide means follows the curved surface of the sheet, and the design of the sheet can be facilitated.
Further, when the light emitting means includes a light source, and the light source is provided on the back side of the seam of the surface material of the sheet main body, it can have an aesthetic appearance that is not different from a conventional sheet when the light emitting means is not emitting light. Therefore, the person who sits on the light-emitting means is not conscious of the light-emitting means, the light-emitting means is unexpected, and the light leaking from the seam is excellent in aesthetic appearance. Furthermore, since light emitted from the light source leaks directly from the seam, it is easy to perform more complicated light emission control.
Further, when the light emitting means is provided on the headrest of the seat body, the visibility of the light emitting means from the outside of the vehicle is improved, and the visibility as a hazard lamp can be further improved.

Hereinafter, the warning light-equipped sheet of the present invention will be described in detail with reference to FIGS.
The sheet with a warning light of the present invention is characterized by comprising a sheet main body having a light emitting means and a blinking control means.
The “seat body” is a seat for a vehicle such as an automobile, and the shape and material thereof are not particularly limited. Further, it can be used as a seat provided at an arbitrary position such as a driver seat, a passenger seat, and a passenger seat. Such a sheet body is usually provided with a frame body and a cushion material, and a surface material covering them.
The “surface material” is not particularly limited in shape and material. For example, examples of the shape include a sheet shape and a plate shape. Examples of the material include synthetic resin, rubber, and metal.
The “hazard lamp” is a lamp used as an emergency blinking indicator. An example of such a lamp is a turn signal lamp. The lighting of the hazard lamp is usually controlled by an independent control circuit that operates by operating the lighting switch of the hazard lamp, a circuit controlled by the ECU, and the like.

The “light emitting means” may be any means as long as it is provided on the sheet and emits light, and any means can be selected. Examples of this include the use of light sources such as LEDs, light bulbs and fluorescent lamps (including cold cathode fluorescent tubes). Moreover, the light emitted from the light source can be guided to an arbitrary place using a light guide means such as a light guide rod and a light guide plate that transmits light emitted from the light source and leaks light from the side surface.
The place where the light emitting means is disposed on the seat body may be at least a position that serves as a backrest and / or a headrest. The backrest (see, for example, the backrest 21 shown in FIG. 1) and the headrest (eg, the headrest 22 shown in FIG. 1). See). Among these, since the visibility of the light emitting means from the outside of the vehicle is improved and the visibility as a hazard lamp can be further improved, the headrest can be a good example. Moreover, you may provide a light emission means in a seat surface (for example, see the seat surface 23 shown in FIG. 1), an armrest, etc. It should be noted that the place where the light emitted from the light emitting means is output is at least a position where the backrest and / or the headrest is located. For example, as shown in FIG. 2, the light emitting means 3 includes a light source 31 and a light guiding means 32. If it is, the light guide means 32 for outputting light may be provided at least on the backrest and / or the headrest.

Arrangement method of the light emitting means can be arbitrarily selected, and the light emitting means may be fixed by any fixing means such as adhesion and fitting so as to be exposed on the surface of the sheet body, or transparent or translucent. A window may be provided on the surface of the sheet main body, and the light emitting means may be fixed to the back side of the sheet main body by the arbitrary fixing means. Furthermore, as illustrated in FIG. 3, light emitting means (light guide means 32 in FIG. 3) can be provided along the back side of the seam 25 of the surface material 24 of the sheet body 2.
The “seam” is formed by sewing adjacent surface materials or connecting them with a tape or the like. In addition, a gap between the surface materials is generated at the seam, and the size of the gap is not limited as long as light from the light emitting means prepared on the back side of the surface material can be visually observed through the gap. For example, the gap may be large enough to be visually recognized (for example, it may be 0.1 mm or more), or the gap may be such that it cannot be visually observed in a range where light leaks (for example, less than 0.1 mm). Can be).
Further, the method of providing the light emitting means along the back side of the seam of the surface material can be arbitrarily selected. For example, the light emitting means can be bonded to the back side of the surface material on one side or both sides of the seam, and can be arbitrarily bonded, adhered and sewn. It can be fixed using fixing means. Furthermore, it can be fixed to the frame body and the cushion material adjacent to the back side of the seam by using any fixing means such as adhesion, adhesion and fitting.

  The “flashing control means” may be any means that can control the light emitting means to emit light in conjunction with the lighting of the hazard lamp, and can be arbitrarily selected. For example, an independent control circuit for controlling the lighting of the hazard lamp and a circuit controlled by the ECU may be used as the blinking control means as they are, or a signal output from each circuit is used as an input signal, and the input signal is In the case of indicating that the hazard lamp is blinking, a circuit that turns on and blinks the light emitting means may be used.

Such a sheet with a warning light is shown in FIGS. The seat with warning light 1 includes a seat body 2 including a backrest 21, a headrest 22, a seating surface 23, and a light emitting unit 3, and a blinking control unit 4.
As the sheet main body 2, a commonly used one can be used. Further, the backrest 21, the headrest 22, and the seating surface 23 are covered with a surface material 24 made of a synthetic resin or the like and a woven fabric or the like.
The light emitting means 3 includes a light source 31 using an LED lamp and a rod-shaped light guiding means 32 made of a translucent resin. The light source 31 is provided at an arbitrary location in the sheet body 2. 3 to 5, the light guide means 32 is sewn so as to pass through the sheet main body 2 and be in contact with the seam 25 on the back side of the surface material 24. Furthermore, one end is connected to the light source 31, and the light emitted from the light source 31 is transmitted inside to leak out from the peripheral surface. As shown in FIGS. 3 to 5, the leaked light leaks to the outside through a gap between the seams 25.
The blinking control means 4 is a drive circuit that inputs a signal indicating that the hazard lamp is being output, which is output from the ECU, and causes the light source 31 to blink in synchronization with the blinking of the hazard lamp.

As shown in FIGS. 4 and 5, the warning light sheet 1 is configured such that when the hazard lamp is blinking, the light emitted from the light source 31 blinked by the blinking control means 4 is guided by the light guide means 32 and the stitches. The seam 25 of the backrest 21, the headrest 22, and the seating surface 23 appears to be shining. Moreover, since the light leaking from the seam 25 of the backrest 21 and the headrest 22 is visible from the outside of the vehicle, the visibility as a hazard lamp can be improved. In particular, since all the light leaking from the seam 25 of the headrest 22 can be seen from the outside of the vehicle, the visibility as a hazard lamp can be further improved.
In addition, since the warning light seat 1 can have an aesthetic appearance that is not a substitute for the conventional seat when the light emitting means 3 is not emitting light, the person sitting on the light emitting means 3 is not aware of the light emitting means 3. It is possible to obtain a sheet that is unexpected in time and that has excellent aesthetic appearance due to light leaking from the seam.

In the present invention, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. That is, the warning light-equipped sheet 1 includes the light source 31 and the light guide unit 32 as the light emitting unit 3, but is not limited thereto, and may be the light emitting unit 3 including only the light source. For example, as shown in FIG. 6, such a warning light-equipped sheet 1 ′ is provided with a light source 33, which is a light emitting means 3 ′ and includes an LED lamp, on the back side of the seam 25. Such a light source 33 is embedded in a cushion material located on the back side of the seam 25.
Further, when the surface material 24 is translucent or semi-translucent, the light emitting means can be provided on the back side other than the seam 25.
