KR-20260062443-A - Active pressure control seat

Abstract

The present invention relates to an active body pressure control seat, and provides an active body pressure control seat that ensures uniform body pressure for the occupant by installing an air pad with a load sensor attached to the front of the seat to measure the occupant's body pressure distribution and then actively adjusting the pressure according to the occupant's body shape. The present invention for achieving the above objective comprises: a seat cushion having a cushion pad with a concave installation groove formed on its upper surface; a seat back having a back pad rotatably installed on the seat cushion and having a concave installation groove formed on its front surface; an air pad installed to be inserted into the installation groove of the cushion pad and the installation groove of the back pad, adjusted to the occupant's physical condition through pressure adjustment, and supporting the occupant's load together with the cushion pad and the back pad; a beam-type air pad capable of performing an auxiliary role for the air pad as a safety device and improving the overall rigidity of the air pad; a separate lumbar air pad designed for the purpose of reinforcing lumbar support for the occupant; and a load sensor installed on the upper surface of the air pad to sense the occupant's load and adjust the pressure of the air pad to the occupant's physical condition.

Claims (5)

1. A seat cushion having a cushion pad with a concave mounting groove formed on its upper surface; A seat back having a back pad rotatably installed on the seat cushion and having a concave installation groove formed on the front surface; An air pad that is installed to be inserted into the installation groove of the cushion pad and the installation groove of the back pad, is adjusted to suit the occupant's physical condition through pressure adjustment, and supports the occupant's load together with the cushion pad and the back pad; An active body pressure control seat characterized by comprising: a load sensor installed on the upper surface of the air pad to sense the load of the occupant and adjust the pressure of the air pad according to the occupant's body condition.
2. In Article 1, The above air pad is, An air pad body installed to be inserted into the interior of the above-mentioned installation groove, with air supplied to the interior to support the load and regulate pressure; An active body pressure regulating sheet characterized by comprising: a beam-shaped air pad installed to extend in the longitudinal direction of the air pad body within the air pad body, serving to improve the rigidity of the air pad and maintain its shape.
3. In Article 2, An active body pressure regulating seat characterized by the beam-shaped air pad being designed such that its lower surface is installed so as to be attached to the lower surface of the air pad and its upper surface is installed so as to be spaced apart from the upper surface of the air pad, thereby enabling it to perform the function of an air pad even when the air pad body is damaged.
4. In Article 1, An active body pressure regulating seat characterized by comprising a separately attached lumbar air pad to significantly increase the protrusion amount of the air pad at the lumbar support position, by additionally installing a lumbar air pad for lumbar support to enhance the occupant's lumbar support force in the air pad installed on the seat back.
5. In Article 1, An active body pressure control seat characterized by a occupant load sensing system in which a film-type load sensor equipped with a weight detection sensor is directly attached to the top of the air pad and formed as a single body with the air pad, thereby enabling accurate measurement of the occupant load value applied to the air pad.

Description

Active pressure control seat The present invention relates to an active body pressure adjustment seat, wherein an air pad with a load sensor attached to the front of the seat is installed to measure the body pressure distribution of the occupant and then actively adjust the air pressure of the air pad according to the occupant's body shape; and to a seat designed to allow the occupant to directly adjust the air pressure of the air pad to change the seating comfort from a hard state to a soft state to suit the occupant's needs. A typical automobile seat is composed of a seat back and a seat cushion, the seat cushion is installed to slide back and forth on the vehicle body, and the seat back is mounted to the rear of the seat cushion so as to be foldable. In addition, various configurations have recently been provided to improve the convenience and safety of drivers and passengers. For example, air cushions are provided to take on the most convenient and suitable shape for the driver and passenger's body types. In this case, the air cushion includes air cushions installed in the lumbar portion and both pelvic portions of the seat back, as well as in the buttock portion, both side portions, and the thigh portion of the seat cushion. In addition, this air cushion structure includes an air pump that supplies compressed air to each of these air cushions and a controller that determines when to supply compressed air. This air cushion structure uses a controller to control the air pump, providing an appropriate amount of air pressure to each air cushion to create a shape suitable for the body. This allows the seat to be adjusted to fit the occupant's body shape by measuring the occupant's weight in real time through a load sensor attached to the top of the air pad. However, the above air cushion can be easily damaged by external impact or sharp tools, so it is installed on the back of the seat back pad, and as a result, its size is limited and the load is supported by the pad, so it has the problem of not being able to perform the load-bearing function.

FIG. 2 is an exploded perspective view showing the seat cushion of an active body pressure regulating seat according to the present invention separated. FIG. 3 is an exploded perspective view showing the seat back of an active body pressure regulating seat according to the present invention separated. FIG. 4 is an exemplary diagram showing a state in which a lumbar air pad is further installed on the back surface of an air pad according to the present invention. FIG. 5 is an exemplary diagram showing a cross-section of an air pad according to the present invention. The configuration and operation of an embodiment of the present invention will be described in detail below in conjunction with the attached drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted.
