A seat device that can easily and positively achieve the conversion of the state of a seat. A leg stand (11) fixed on a floor surface, a movable stand (20) supported by the leg stand (11) so as to be able to advance/retract in front and back directions, an underframe (30) of the seat supported by the movable stand (20) so as to be rotatable in forward and backward directions, and an interlocking mechanism (50) that interlocks advancement/retraction of the movable stand (20) with rotation of the underframe (30) are included. The interlocking mechanism (50) includes a plurality of cam grooves (51) that are provided to the leg stand (11), and regulates the trajectory of rotation or advancement/retraction of the underframe (30), a rotary member (52) that is provided to the underframe (30), and is engaged with the cam grooves (51) so as to be movable along the cam grooves (51), the engagement being always maintained to at least any portion of the cam grooves (51), and a switching portion (53) that is provided at a branch point in the cam grooves (51), and can switch the direction to which the rotary member (52) is guided at the branch point.

Described are modular leg assemblies for passenger seats. The modular leg assemblies can include a universal first leg member, a universal second leg member, a size specific member, and a universal seat frame tube receptor. The universal first leg member may be coupled to a first seat track fitting. The universal second leg member may be coupled to a second seat track fitting. The size specific member may be coupled to the universal first leg member and to the universal second leg member. At least one of the universal second leg member or the universal seat frame tube receptor can include a set of attachment points for coupling the universal seat frame tube receptor to the universal second leg member.

A seat device that can easily and reliably achieve the conversion of the state of a seat. A rotation mechanism (40) that rotates the seat about a rotation axis, a sliding mechanism (14) that advances and retracts the seat together with the rotation mechanism (40) from a fixed side, and a drive mechanism (50) that sequentially and directly drives each of the sliding mechanism (14) and the rotation mechanism (40) are included. The drive mechanism (50) includes a power source (51) provided in the fixed side of the seat, and transmission means for directly driving the sliding mechanism (14) first, and then directly driving the rotation mechanism (40), in a process of converting the state of the seat with power of the power source (51). Here, the transmission means is formed by a sprocket (58) rotated by torque of a motor (51), and many holes (59) with which the sprocket (58) is rotatably engaged to transmit the power.

A polycarbonate resin composition comprising, 100 mass parts of (A1) a polycarbonate resin that contains a polycarbonate resin having a structural unit of the following general formula (1) and (A2) a polycarbonate resin having a structural unit of the general formula (2) in a mass ratio (A1)/(A2) of 100/0 to 10/90; 3 to 20 mass parts of a phosphorus flame retardant (B); 2 to 20 mass parts of a silicone flame retardant (C); and 3 to 100 mass parts of an inorganic filler (D), wherein the phosphorus flame retardant (B) is a phosphazene compound and/or a condensed phosphate ester, [C1] ##STR00001##

Described are table assemblies for a passenger seat. The table assemblies may include a paddle arm, a table support, and a leveling assembly. A first end of the paddle arm may include a paddle arm tab extending outwards from the paddle arm. The table support may be pivotably connected to the first end and configured to support a table. The table support may include a top side that defines a latch receiving area. The leveling assembly may include a latch and a latch adjuster. The latch may be pivotably supported on the table support within the latch receiving area. The latch adjuster may selectively engage a first end of the latch and control a tilt angle range of the table support. The latch adjuster may engage the latch at a first tilt angle, and the paddle arm tab may engage the latch at a second tilt angle.

A rail vehicle is provided with an open passenger space equipped with a perch seat assembly. The perch seat assembly includes a perch seat, a table, and a transition portion joining the table to the perch seat. The table has a horizontal working surface which extends from a wall so that at least a portion of the table extends in front of the perch seat. The transition surface provides a continuous surface between the perch seat surface and the table surface so as to provide a smooth transition.

A polycarbonate resin composition comprising, 100 mass parts of (A1) a polycarbonate resin that contains a polycarbonate resin having a structural unit of the following general formula (1) and (A2) a polycarbonate resin having a structural unit of the general formula (2) in a mass ratio (A1)/(A2) of 100/0 to 10/90; 3 to 20 mass parts of a phosphorus flame retardant (B); 2 to 20 mass parts of a silicone flame retardant (C); and 3 to 100 mass parts of an inorganic filler (D), wherein the phosphorus flame retardant (B) is a phosphazene compound and/or a condensed phosphate ester,
