Abstract: A travel restricting device is for restricting the traveling of a transport vehicle along a travel rail in a transport facility. The transport vehicle includes a wheel that rolls on a travel surface of the travel rail, a drive device that drives the wheel, and a bumper that causes the drive device to undergo an emergency stop. The travel restricting device includes a mounting section mountable on the travel surface, and a standing section that can be disposed extending upward beyond the travel surface. The standing section includes a facing section arranged at a position facing the bumper from a distancing side in the travel direction while the mounting section is mounted on the travel surface. The mounting section includes an underlay section positioned relative to the facing section so as to be pressed under the wheel while the bumper is in contact with the facing section.

Abstract: A vehicle seat includes an internal support member for supporting a seat occupant. The internal support member includes a main body in plate or sheet form positioned within a seat cushion frame, a pair of inclined portions extending laterally from a part of either lateral side of the main body with an upward slant, and front and rear mounting portions engaged by front and rear cross members of the seat cushion frame. A pressure sensor is mounted on a part of an upper surface of the internal support member located ahead of the inclined portions. The main body of the internal support member is provided with a pair of openings located on either side of the pressure sensor, and a connecting portion connecting the pressure sensor with a part of the front mounting portion. The pressure sensor and the openings are spaced from the front edge of the main body.

S-alkyl 5-[(1-alkoxy)ethoxy]alkanethioate represented by formula (1), and a perfume composition comprising the S-alkyl 5-[(1-alkoxy)ethoxy]alkanethioate represented by formula (1) as an active ingredient. In the formula (1), R1 represents an alkyl group having 1 to 9 carbon atoms, R2 represents an alkyl group having 2 to 4 carbon atoms, and R3 represents a methyl group or an ethyl group.

Abstract: To secure both flexibility and rigidity of a pressure-receiving member, a pressure-receiving member capable of moving rearward in a state of receiving a load from a back of an occupant is included in a seat back of a conveyance seat for supporting the back of the occupant. The pressure-receiving member has a load-receiving portion which receives the load from the back of the occupant at a front face, and the load-receiving portion includes a load-receiving portion piece formed so that a length in a vertical direction of the seat back is shorter than a length in a seat width direction, and a rear reinforcement rib protruding along a thickness direction of the load-receiving portion from the load-receiving portion piece and extending along the seat width direction.

Abstract: A mat attachment structure of a seatback includes: a guide wire attached to the mat and provided, at the distal end part, with a straight portion extending in a longitudinal direction of the seatback frame on a tip side of the seatback frame or its root side; and a through-hole formed in the seatback frame and through which the straight portion is insertable. The through-hole is provided with a protruding part which includes a high protruding portion and a low protruding portion formed adjacent to the high protruding portion. In a first movement of the mat, the straight portion moves in a de-insertion direction while coming into contact with the high protruding portion. As the amount of movement of the mat gets larger than the amount of movement of the first movement, a contact position between the straight portion and the protruding part moves toward the low protruding portion.

Abstract: A mat attachment structure of a seatback includes: a guide wire attached to the mat and provided with a width-direction extending part extending in s width direction of the seatback frame on a tip or root side of the seatback frame; and a holder having a base part which holds the width-direction extending part so as to be rotatable around an axis of the width-direction extending part and an attachment part attached to the seatback frame. When a force exceeding a predetermined value in a direction to separate from the seatback frame is applied from the width-direction extending part to the holder, the force being due to the force from the back of the occupant that the mat receives, the width-direction extending part departs from the base part or the holder departs from the seatback frame, so that the width-direction extending part is separated from the seatback frame.

Abstract: It is intended to expand a space at a back portion of a lower portion of a seat. A seat frame includes a lower frame configured to couple lower portions of side frames arranged on right and left sides. The lower frame includes a back wall portion provided on a back side, a front wall portion provided in front of the back wall portion, and a coupling portion that couples lower ends of the back wall portion and the front wall portion. The back wall portion includes a pair of side portions forming ends in a seat width direction and each formed along the outer shapes of the side frames, and an inclined portion provided between the side portions and inclined such that a lower end is positioned in front of an upper end. The inclined portion is provided in front of the side portions.

Abstract: A seat lifter structure which can maintain the engagement of the gear of the sector and the pinion of the brake unit and prevent a fall down of the seat back to a front side, even when a large force to a front side is exerted with respect to the seat back is provided. It raises or lowers a cushion seat (ST1) by raising or lowering a side frame (2) built into the cushion seat (ST1) with respect to a fixing member (61).

Abstract: Provided is a conveyance seat configured for adjustment of a deflection amount of a seat forming the conveyance seat, i.e., cushion properties of the seat.
