KR-20260062529-A - Reclining vehicle seat to prevent entrapment accidents

Abstract

The present invention relates to a vehicle reclining seat in which the seat back rotates, and more specifically, to a vehicle reclining seat that prevents pinching accidents, which can prevent the bodies of passengers in the adjacent and rear seats from being pinched into the seat back during reclining operation. A vehicle reclining seat that prevents pinching accidents according to the present invention comprises: a seat body (10) having a seat cushion (20) and a seat back (30); a recliner (400) installed on the seat body to provide a forward and backward rotational force to the seat back; a contact sensor (800) installed on the rear of the seat back to detect pressure on the seat back and output a contact signal; and a control unit that stops the operation of the recliner only when a contact signal is input from the contact sensor.

Claims (5)

1. A seat body equipped with a seat cushion and a seat back; A recliner installed on the above seat body to provide forward and backward rotational force to the seat back; A contact sensor installed on the rear of the seat back to detect pressure on the seat back and output a contact signal; and A vehicle reclining seat that prevents pinching accidents, comprising a control unit that stops the operation of the recliner only when a contact signal is input from the contact sensor.
2. In paragraph 1, The above contact sensor is A vehicle reclining seat formed of a flexible material that prevents pinching accidents by being positioned in various paths on the rear of the seat back.
3. In paragraph 1, The above contact sensor is Elastic tube; A fixing part extending from both sides from the elastic tube and fixed to the rear surface of the seat back; and A vehicle reclining seat that prevents pinching accidents, comprising a pair of electrode pieces formed to face each other on the inner wall surface of the elastic tube so as to make contact when an external force is applied to the elastic tube, and outputting a contact signal to the control unit only when contact is made.
4. In paragraph 3, The above electrode piece is integrally molded along the elastic tube; A vehicle reclining seat that prevents pinching accidents, wherein a conductive protrusion is formed on the inner surface of the elastic tube to surround and protect the electrode piece while expanding the contact area of the electrode piece.
5. In paragraph 3, The above recliner is electrically operated; A vehicle reclining seat in which the above contact sensor is electrically connected to the recliner and sensing is performed only when the recliner is operated, thereby preventing pinching accidents.

Description

Reclining vehicle seat to prevent entrapment accidents The present invention relates to a vehicle reclining seat in which the seat back rotates, and more specifically, to a vehicle reclining seat that prevents pinching accidents, which can prevent the bodies of passengers in the adjacent and rear seats from being pinched into the seat back during reclining operation. With the recent increase in leisure activities and the expansion of the campervan market, regulations that previously limited vehicles eligible for conversion to campervans to passenger vans have been expanded to include all vehicle types (passenger, cargo, special, and passenger vans), and the demand for simple interior conversion systems is continuously increasing in response to changes in market demand. One of the representative demands is the application of full-flat seats, which allow the second and third row seats to be fully folded flat, making them a preferred vehicle for campers' car camping. These conventional full-flat seats require the seatback to be rotated backward to achieve a full-flat state, and if care is not taken, there is a very high possibility that parts of the body, such as the arm, shoulder, or head of a passenger in the adjacent seat who is resting in the reclining position, will get caught in the seatback. Once a pinching accident occurs, it leads to serious injuries, so improvements are urgently needed. In addition, passengers in the rear seats or items loaded in the rear may be injured or damaged if not careful, as they are pressed against the seatback of the full-flat seat, causing many inconveniences in use. FIG. 1 is a rear perspective view of a vehicle reclining seat that prevents pinching accidents according to the present invention. FIG. 2 is a rear perspective view showing the frame configuration of the sheet body constituting the present invention. FIG. 3 is a perspective view of a key part showing the frame configuration of a sheet body constituting the present invention. FIG. 4 is a side view of a vehicle reclining seat that prevents pinching accidents according to the present invention. FIG. 5 is a side view showing the configuration of the frames of FIG. 4. FIG. 6 is a side view showing a fully flat state of a vehicle reclining seat that prevents pinching accidents according to the present invention. FIG. 7 is a side view showing the configuration of the frames of FIG. 6. FIG. 8 is a cross-sectional view along line VIII-VIII of FIG. 1. The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments based on the accompanying drawings. Prior to this, terms and words used in this specification and claims must be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Furthermore, the terms and words used in this specification and claims are used merely to describe specific embodiments and are not intended to limit the invention. For example, a singular expression includes a plural expression unless the context clearly indicates otherwise. Furthermore, terms such as "include," "equip," or "have" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Furthermore, when a part such as a layer, membrane, region, or plate is said to be "above" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when a part such as a layer, membrane, region, or plate is said to be "below" another part, this includes not only the case where it is "directly below" the other part, but also the case where there is another part in between. In addition, terms including ordinal numbers, such as "first," "second," etc., used in this specification may be used to describe various components, but said components are not limited by said terms, and said terms are used solely for the purpose of distinguishing one component from another. Hereinafter, in describing an embodiment of the present invention in detail with reference to the drawings, the same reference numerals are used for identical components, and for clarity, only the different parts are described primarily to avoid duplication as much as possible. As illustrated in FIGS. 1 to 8, a reclining seat for a vehicle according to the present invention comprises a seat body (10) having a seat cushion (20) and a seat back (30), a recliner (400) that applies a forward and backward rotational force to the seat back (30), a contact sensor (800) installed on the rear of the seat back (30) t
