  • Patent number: 11063225
    Abstract: A highly reliable light-emitting element having high emission efficiency is provided. The light-emitting element includes a light-emitting layer including a first organic compound and a guest material. The first organic compound has a substituted or unsubstituted carbazole skeleton. In the light-emitting layer, the weight ratio of a hydrocarbon group substitution product in which at least one of hydrogen atoms in the first organic compound is substituted by a hydrocarbon group having 1 to 6 carbon atoms to the first organic compound is greater than 0 and less than or equal to 0.1.

  • Patent number: 10640013
    Abstract: The present invention has an object to provide a seat for vehicles in which walk-in operation can be cancelled by simple operation. A seat for vehicles includes: a mechanism to shift a seat cushion (2) from a seating position to an escape position by operation of an operation part (9); and a walk-in cancel mechanism (400) for cancelling walk-in operation which restrains a seat back (3) from rotating to a fully tilted-down position of the seat back (3) when the seat cushion (2) is shifted from the seating position to the escape position and the seat back (3) is rotated to a middle tilted position, and also switches a slide rail device in a locked state to an unlocked state, in which the walk-in cancel mechanism (400) is automatically operated in conjunction with operation of the operation part (9).

  • Patent number: 10391897
    Abstract: The present invention has an object to provide a seat for vehicles in which a seat cushion flip-up mechanism can be space-saving. In a seat for vehicles which has a flip-up mechanism to shift a seat cushion frame (200) disposed on a base part (5) from a normal seating posture (200-1) to a flipped-up posture (200-2), the flip-up mechanism includes: a support leg part (301) having one end connected to the seat cushion frame (200) rotatably around a first rotation shaft (303) and the other end connected to the base part (5) rotatably around a second rotation shaft (302); a guide part (201a) to be engaged with the one end of the support leg part (301) to guide the one end so as to lift the one end; and a coil spring (305) applying a biasing force so as to have the one end guided by the guide part (201a) and flip up a portion (303) connected with the seat cushion frame (200).

  • Patent number: 10369911
    Abstract: The purpose of the present invention is to provide a headrest to be infallibly locked when returned from a forward tilted position to a using position, without requiring high part accuracy and assembly accuracy. A vehicle seat headrest (4) according to the present invention, having: a stay (402) held on the seat back side; and a headrest main body (4A) supported forward rotatably from a using position with respect to the stay (402), includes: a locking mechanism (500) that fixes a rotation position of the headrest main body (4A) with respect to the stay (402) in the using position; and a stopper mechanism (600) that is not engaged with a regulation part in the using position, but is engaged with the regulation part when the headrest main body (4A) is tilted backward from the using position, to regulate backward tilting of the headrest main body (4A).

  • Patent number: 10272811
    Abstract: The object of the present invention is to provide a headrest capable of, when a user touches the headrest, preventing the user's finger from being inserted into the inner space of the headrest. The vehicle seat headrest according to the present invention includes: a stay (402) held on the seat back side; and a headrest main body (4A) supported forward rotatably from a using position with respect to the stay (402). The headrest main body (4A) has: a main body frame (401) forming a strength member; hinge parts (403a), (403b) which connect the main body frame (401) rotatably with respect to the stay (402); a locking mechanism (500) which fixes the main body frame (401) in the using position with respect to the stay (402); and cushion material (407) which covers the main body frame (401) and the hinge parts (403a), (403b). In the vehicle seat headrest, a resin lower cover (408), having an opening (408a) through which the stay (402) is inserted, covers a lower surface of the headrest main body (4A).
