Abstract: The present invention relates to a reclining apparatus for a rear seat of a vehicle, having a back frame having a upper end and a lower end; a cushion frame having a front side and a back side, wherein the back side of the cushion frame is pivotally connected to the lower end of the back frame; a back frame locking module disposed on the upper end of the back frame, the back frame locking module removably engageable to a body panel and acting as a pivot center when engaged with the body panel; and a guide module configured to guide the cushion frame pivotally connected to the back frame so that the lower portion of the back frame pivots about the upper portion when the cushion frame slides up forward or down rearward to allow the back frame to move between an upright position and a reclined position.

Abstract: The present invention relates to an apparatus for adhering a soft slab and a covering material together. The apparatus for adhering the soft slab and the covering material together includes: a moving unit consisting of a plurality of rollers for moving the soft slab; a conveyor unit including a belt configured such that air passes through the top and bottom surface thereof, and a driving unit for driving the belt, the conveyor unit being intended for transferring a covering material seated on the top surface of the belt toward an adhesive surface of the soft slab; and an air suction unit provided at the bottom surface of the belt so as to suction air such that the covering material is tightly attached onto the top surface of the belt, thereby attaching the covering material onto the adhesive surface of the soft slab without generating pleats.

Abstract: Disclosed is an antimicrobial bio polyurethane foam and a method for manufacturing thereof, and more specifically, a polyurethane foam which comprises a reaction product of a resin premix comprising the biopolyol in an amount of 5 to 30 wt % based on total weight of the resin premix, and a prepolymer. The antimicrobial bio polyurethane foam is enhanced in an antimicrobial property by maximizing the content of the biopolyol.

Abstract: Disclosed is an antimicrobial bio polyurethane foam, and more specifically abio polyurethane foam: which is polyurethane foam comprising a reaction product of a resin premix, which comprises biopolyol of about 5 to 20 wt %, and isocyanate; applied to a car seat and the like; and which is enhanced in an antimicrobial property through use of the biopolyol.

Abstract: Disclosed is a multi-functional bio polyurethane foam, and more specifically a multi-functional bio polyurethane foam which is polyurethane foam comprising a reaction product of a resin premix, which comprises about 5 to 20 wt % biopolyol, and isocyanate. The multi-functional bio polyurethane foam may be applied to a car seat and the like, and shows the same level of physical properties as the conventional polyurethane foam manufactured from the petroleum-based polyol, and further provides enhanced antimicrobial function and minimized vibration transmissivity.

Abstract: The present invention relates to a reclining apparatus for a head rest of a rear seat that includes: a reclining motor operably coupled to an integral lead screw; a carrier thread fastened to the integral lead screw; and a link module configured to transmit operation force from the carrier to a head rest module, wherein the head rest module angle is adjusted in a forward/rearward direction by the operation force from the carrier and the link module.

Abstract: A system and method is provided for observing a heart rate of a passenger. The system for observing a heart rate of a passenger includes a plurality of different types of heart rate sensors provided on a seat cushion or a seat back, and a control unit for collecting waveforms of the heart rate sensors for respective sensor types, computing accuracies of the waveforms for respective sensor types at each unit time, selecting a waveform having a highest accuracy at each unit time, and then calculating a heart rate.
