Abstract

PROBLEM TO BE SOLVED: To surely fix a sensor or the like to a prescribed position by constituting a pad of a main body having a storage space part and a block body which is stored in the storage space part and supported by means of a frame and arranging a sensor and a heater in a part between the top surface of the block body and a seat surface side in the storage space part. SOLUTION: This pad main body 1 is foam-molded by a molding, the storage space part 10 is arranged in the lower part of the center part of a seat surface and also the block body 2 is stored in the part 10. It is favorable that the upper part of the part 10 is formed by a soft material such as slab material and an open-cells foam body. The block body 2 is molded to be a shape which is fitted to the inside of the part 10 by a urethane foam being the same as that of the main body 1 or the harder urethane foam with a high density compared with the main body 1. The sensor or the heater 3 is adhered to the top surface 2A of the block body 2 and held by the block body 2 onto the ceiling surface 10A being the seat surface side in the storage space part 10 and a harness 30 is drawn outward from the frame 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat (seat) with a built-in sensor or heater, and more particularly, to a vehicle seat with a built-in seat sensor or heater that presses and adheres a skin to a foam pad.

[0002]

2. Description of the Related Art Some conventional assistant seats have a built-in sensor for detecting the occupant's seating. In addition, heaters are built into driver seats and the like. In this sensor or heater, a concave portion for accommodating a sensor is formed on a seating surface of a foam pad, and the sensor is accommodated in the concave portion and is attached to the pad. Then, the skin is adhered to this pad to form an adhesive sheet.

[0003]

By the way, the above-mentioned conventional products are obtained by bonding a single-piece skin to a pad instead of a skin consisting of three layers of a skin material, a foam wadding, and a wading cover. The heater appears in the form of irregularities on the outside, and not only has a poor appearance, but also has a problem of giving a foreign-body sensation. For this reason, an adhesive sheet for bonding a single skin has a slab material interposed between the sensor, the heater and the skin.

[0004] However, if the sensor or heater is housed in the recess of the pad together with the slab material and then the skin is pressed onto the pad and adhered thereto, the sensor or heater is displaced and it is difficult to fix it properly at a predetermined location.

Further, since the harness of the sensor or the heater must be exposed to the outside from the seating surface side of the seat and wired to the bottom side, the wiring work of the harness requires man-hours, and the harness is not connected to the outside of the seat. There was a problem that it was in the way because it protruded.

Accordingly, an object of the present invention is to eliminate the disadvantages of the conventional product in a vehicle seat having a sensor or heater built therein by bonding the skin to the pad.

[0007]

According to the present invention, there is provided a sensor-equipped vehicle seat according to the present invention, comprising a foam pad supported by a molded frame and a foam, and a skin adhered to the pad. In a vehicle seat having a sensor or a heater, the pad includes a main body having a storage space below a seating surface, and a block body stored in the storage space of the main body and supported by the frame, The sensor or heater is disposed between the top surface of the block body and the seating surface side in the storage space.

Accordingly, the sensor or the heater does not directly contact the skin, and even if a single thin skin is used, the seating surface of the seat does not become uneven due to the sensor.

Preferably, the upper portion of the sensor or the heater in the main body is formed of a slab material, so that the cushioning property of the seated portion of the seat is improved, and the detection performance of the sensor and the thermal conductivity of the heater are improved. It is not spoiled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 shows a vehicle (automobile) seat according to the present invention, in which (1) is a pad body, (2) is a block body, (3) is a sensor or heater, and (4) is a body (1). ) And the frame supporting the block body (2), and (5) the epidermis.

The main body (1) is foam-molded by a mold, and as shown in FIG. 2, a storage space (10) is formed below a central portion (2) of the seating surface. The block (2) is stored in the space (10).

The upper part of the storage space (10) in the main body (1) is preferably formed of a soft material such as a slab material or an open-cell foam, but the entire main body (1) is formed of the same urethane foam. You may.

The block body (2) is the same urethane foam as the main body (1) or a rigid or high-density urethane foam with respect to the main body (1), and has a storage space (1) in the main body (1).
It is molded into a shape that fits inside 0).

The sensor or heater (3) has a conventionally well-known structure used for automobile seats, is attached to the top surface (2A) of the block body (2), and has a storage space for the main body (1). The block (2) sandwiches the ceiling surface (10A) on the seating surface side in the portion (10).

The harness (30) of the sensor or heater (3) is drawn out of the frame (4) through the side wall of the block (2).

Accordingly, the harness (3) is provided on the frame (4).
The through hole for passing 0) is opened. The illustrated frame (4) is a pan-type frame, which supports the block body (2) and the main body (1), and has a terminal of the skin (5) hooked to the outer peripheral edge.

The skin (5) is made of a single piece of woven fabric, brushed fabric, thin fabric such as leather (artificial or natural), and is adhered to the pad body (1) with an adhesive.

This bonding is performed by pressing the skin (5) on the main body (1). At that time, it is preferable to perform the operation before the block (2) with the sensor or the heater (3) is stored in the main body (1) so as not to damage the sensor and the heater.

[0019]

According to the present invention, since the sensor or heater does not come into direct contact with the skin adhered by pressing to the pad, the sensor or heater can be accurately fixed at a predetermined position.

In addition, even if a thin skin is used, the sensor or heater does not give a foreign-body sensation and does not appear unevenly on the outer surface of the sheet.

Furthermore, since the harnesses of the sensor and the heater can be wired directly to the bottom side of the seat without exposing the harness of the seat to the seating surface side, the number of man-hours for attaching the harness can be reduced, and a seat having good appearance quality can be formed. .
