Description

[Detailed description of the invention] <<Industrial Application Field>> The present invention relates to a so-called reclining seat, which is a vehicle seat equipped with an electric reclining mechanism, and specifically takes safety measures and noise prevention measures during reclining operation. Regarding reclining seats with music boxes.

《Prior art》 As shown in Fig. 4, a vehicle seat has a rear seat 1
Generally, the front seat 2 is of a fixed type, and the front seat 2 is provided with a reclining mechanism that allows the seat back 2a to be tilted rearward.

Vehicle seats equipped with an electric reclining mechanism using an electric motor as a power source have been generally known.

<<Problems to be Solved by the Invention>> By the way, when a seat back is tilted rearward by the electric reclining mechanism, if there is a person sitting in the rear seat, the seat back may come into contact with the person sitting in the rear seat.

In this case, the electric reclining mechanism always tilts the seatback backwards with a certain force, so if the rear seat occupant is unaware of the tilting of the seatback, he or she may become caught between the seatback and the rear seat. be.

Further, in the case of an electric reclining mechanism, there is a problem in that the operating sound of the electric motor becomes harsh to the ears.

An object of the present invention is to provide an electric reclining seat that can ensure safety during reclining operation and prevent noise during reclining operation.

<Means for Solving the Problems> The electric reclining seat of the present invention has a scale board on the seat cushion side, a drum with pins on the outer periphery for playing the scale board, and a pair of arm plates on the seat back side. It is characterized in that it is attached so as to be rotatable integrally with the shaft that connects it, and that the sound is always produced in conjunction with the rotation of the seat bag while the seat bag is rotating.

《Operation》 When the reclining operation is in progress, a music box sounds in conjunction with the start of the seat back tilting to notify the rear seat occupants that the reclining operation is in progress, and the sound of the music box drowns out the harsh operating sound of the electric motor.

<<Example>> FIG. 2 shows a reclining mechanism for a reclining seat with a music box according to the present invention.

Reference numerals 11 and 12 in the figure indicate base plates fixed to the frame of the seat cushion (not shown), and arm plates 13 and 14 fixed to the frame of the seat bag are rotated on these two base plates 11 and 12, respectively. It is attached so that it can move freely. These two arm plates 13 and 14 are connected to each other by a shaft 15.

One base plate 12 is provided with a drive unit 17 that rotates an arm plate 14 attached thereto and an arm plate 13 connected by a shaft 15. This drive section 17 is
An electric motor 18 is used as its power source.

A music box 20 according to the present invention is attached between the base plate 11 and the arm plate 13.

Specifically, as shown in FIG. 1, a U-shaped bracket 21 is attached to the base plate 11 so as to sandwich the shaft 15 from both sides. Extending to the shaft 15 side, the scale board 2
2 and 23 are attached.

Shaft 15 fixed to arm plate 13
A drum 24 is attached to the drum 24, which is sandwiched between the scale boards 22 and 23 and rotated to play the scale boards 22 and 23 with a pin 24a provided on the outer periphery of the drum 24.

As shown in FIG. 3, the scale boards 22 and 23 are pivotally supported on the upper surface of the bracket 21, and are constructed so that they can freely rotate only upwards as shown by phantom lines in the figure. And the drum 24 is
By this rotation, only one of the two scale plates 22 and 23 is played by its pin 24a, and the other is made to spin idly.

In the reclining seat with a music box configured as described above, when a person sitting on the seat tilts the seat back rearward using the reclining mechanism, the shaft 15 fixed to the arm plates 13 and 14 rotates, and the drum 24 plays the scale board 23 to make music. This allows the person sitting in the rear seat to know that the seat back has started moving, and to alert the person sitting in the front seat if the seat back is about to come into contact with his or her body.

When the seat back is tilted backwards and then returned to its original position, the drum 24 rotates in the opposite direction to the above case and plays the other scale board 22 to produce music.

Thereby, the rear seat occupant can reliably know the tilting movement of the seat back by the reclining mechanism, and can ensure safety during the reclining operation.

Further, since the music box is always on during the reclining operation, the harsh sound of the electric motor 8 can be prevented.

In the above embodiment, the drum 24 is directly fixed to the shaft 15, but the drum 24 may be fixed to a shaft other than the shaft 15 and both shafts may be connected by a gear.

<<Effects of the invention>> According to the reclining seat with a music box of the present invention, a musical scale board is provided on the seat cushion side,
A drum having a pin on its outer periphery for playing the scale board is attached so as to be rotatable integrally with a shaft connecting a pair of arm plates on the seat back side, and is constantly linked to the rotation of the seat back while the seat back is rotating. By making it sound, the drum rotates together with the shaft in conjunction with the rotation of the seat back, and the pins installed on its outer periphery play the scale board on the seat cushion side, producing sound. , will be sounded constantly to notify rear seat occupants of the rearward tilting of the seat back.
It is possible to instruct the front seat occupant to stop the reclining operation before the passenger gets caught between the seatback and the rear seat, making it possible to prevent the rear seat occupant from being pinched by the front seat.

Further, in the present invention, since the sound is constantly emitted while the seatback is tilted, it is possible to prevent the operation sound of the electric motor on the reclining mechanism side from being muted and annoying to the occupants.
