Abstract: Disclosed is an apparatus and method for processing a multichannel audio signal. A multichannel audio signal processing method may include: generating an N-channel audio signal of N channels by down-mixing an M-channel audio signal of M channels; and generating a stereo audio signal by performing binaural rendering of the N-channel audio signal.

Abstract: A multilayer electronic component includes: a body including a plurality of dielectric layers and internal electrodes disposed to face each other with each of the plurality of dielectric layers interposed therebetween; and external electrodes connected to the internal electrodes and disposed on outer surfaces of the body, wherein each of the plurality of dielectric layers includes a BaTiO3-based base material main component and an accessory component including dysprosium (Dy) and terbium (Tb), a content of terbium (Tb) is 0.2 mol or more and less than 1.0 mol based on 100 mol of the base material main component, and the dielectric layer includes a plurality of dielectric crystal grains having a particle size of 60 nm or more and 250 nm or less at a point (D50) at which a cumulative volume is 50% in a cumulative particle size distribution according to a particle size distribution system.

Abstract: A leg rest apparatus includes a base bracket mounted below a seat cushion of a vehicle seat, a rear link coupled to a lateral portion of the base bracket, a front link coupled to the lateral portion of the base bracket and positioned above the rear link, a main link hingedly coupled to one end of the rear link and a middle portion of the front link, a support link coupled to one end of the front link, and a leg rest link coupled to the main link and one end of the support link.

Abstract: A device for preventing rotation of a vehicle seat rail is described. The device prevents an upper rail on the center side of a vehicle from rotating when a forward load is applied to a vehicle seat, thereby preventing a lock plate from being fractured due to rotation of the upper rail.

Abstract: A vehicle seatback folding device includes: a cushion bracket; a back side frame rotating on the cushion bracket; a spring mounting bracket coupled to rotate integrally with the back side frame around a hinge-coupling part; a return spring for applying, to the back side frame, elastic restoring force for rotating the back side frame in the folding direction of a seatback; and a reverse spring supported in a state in which a first end portion is caught by the spring mounting bracket and a second end portion is caught by a first spring support end.

Abstract: A device for tilting a seat cushion of a fold and dive seat includes: a pair of seat cushion side frames spaced apart from each other; seat back side frames connected to the pair of seat cushion side frames; a seat cushion main-frame connected to the seat back side frames; guide brackets, one of which disposed on a first side of a front portion of the seat cushion main-frame and another of which disposed on a second side of the front portion of the seat cushion main-frame, wherein each of the guide brackets has a longitudinal through-hole; a tilting support bar, both ends of which extend through the through-holes, respectively; tilting support links, each of which connected between the tilting support bar and each seat cushion side frame; a mounting bracket disposed on the front portion; and a tilting drive device disposed between the mounting bracket and the tilting support bar.

Abstract: A seat adjustment apparatus for a vehicle includes: a set bracket having a rear part to which a back frame is rotatably connected; and a cushion frame disposed on an upper side of the set bracket and to be tilted by a link mechanism. In particular, the link mechanism includes: a first link member which is hinge-engaged with a front part of the set bracket, connected to a driving unit and supports a front part of the cushion frame to make the front part of the cushion frame ascend and descend by the driving unit; a second link member hinge-engaged with a rear part of the set bracket and the cushion frame to guide the rear part of the cushion frame; and a third link member hinge-engaged with the set bracket and the cushion frame to determine a tilting position of the cushion frame when the cushion frame ascends.
