Abstract: A charge port device includes a charge port provided in a port accommodation recess and a lid for concealing the port accommodation recess. A latch is provided in the port accommodation recess on an opposite side to a lid hinge with respect to the charge port. A slit is formed between a surface of a vehicle body and an outer circumferential edge of the lid while the lid is closed. A lamp is provided at a position in the port accommodation recess between the latch and the slit on an opposite side to the lid hinge with respect to the charge port and the position is not visible from outside while the lid is closed. Formed is a light-guiding reflection path that guides a light emitted from the lamp toward the above-mentioned slit as an indirect light by reflecting the light while the lid is closed.

Abstract: A controller, which serves as a pressure-feeding control portion, drives an air pump to pressure-feed air to massage airbags located in a seat. In addition, the controller, which serves as an inflation-deflation control portion, performs massage control that inflates and deflates the airbags while keeping the air pump driven by controlling the operation of intake-discharge valves in second flow passage (branch lines), which connects the air pump to the airbags. Furthermore, the controller, which serves as a decompression control portion, opens a discharge valve, which is located upstream of the intake-discharge valves, in a state in which the airbags are deflated during the massage control.

Abstract: A vehicle seat device includes a reproduction control portion configured to inflate an airbag provided in a seat based on an internal pressure target value, an occupant detection portion configured to detect a seated state in which an occupant is seated on the seat, a body size detection portion configured to detect a size of the occupant, and a correction amount calculation portion configured to calculate, based on the size of the occupant, a correction amount to be used to correct the internal pressure target value in a non-seated state in which the occupant is not seated on the seat.

Abstract: A pneumatic pressure control method for a vehicle seat includes: repeatedly detecting an internal pressure of a bladder provided inside the vehicle seat at intervals; correcting the internal pressure of the bladder based on a differential pressure between a detection value and a target value; and lengthening a detection interval to detect the internal pressure depending on a time elapsing from starting of the vehicle.

Abstract: A vehicle seat device includes: a plurality of air bags configured to be provided inside a seat; a flow path having a shared section to communicate with each of the air bags; a plurality of intake valves each of which is arranged at a flow path position at an upstream of each of the air bags when air is pumped into each of the air bags; a plurality of exhaust valves arranged at flow path positions communicating with the shared section; and a control device configured to control operations of the intake valves and the exhaust valves, in which the control device adjusts a discharge speed of internal air by selectively opening the exhaust valves when the internal air of each of the air bags is discharged.

Abstract: A pneumatic control device for a vehicle seat includes a forcible-delivery control unit, an opening-closing control unit, and a residual pressure release control unit. The forcible-delivery control unit drives an air pump to forcibly deliver air to an airbag, which is provided in a seat. The opening-closing control unit opens and closes an inlet valve, which is provided in a passage of the air. The passage is in communication with the airbag. The residual pressure release control unit opens an outlet valve provided in the passage on an upstream side of the inlet valve after driving of the air pump is stopped, thereby releasing the air sealed on the upstream side of the inlet valve in a closed state from the passage.

Abstract: An air pressure control device of a vehicle seat includes: a bulging shape forming unit configured to form a bulging shape on a seat surface by expanding air bags configured to be provided inside a seat; a bulging shape moving unit configured to move a position of the bulging shape formed on the seat surface by each corresponding air bag by sequentially expanding and contracting a plurality of air bags aligned in a direction along the seat surface in an arrangement direction of the air bags; and a pumping capacity adjusting unit configured to increase a pumping capacity of an air pump that pumps air into each air bag as a protrusion amount of the corresponding bulging shape increases when a formation position of the bulging shape is moved.

Abstract: A polyacetal resin composition produced by melt-kneading polyacetal, polyfluorovinylidene and optionally, an organic lubricant at a temperature higher than the melting point of each of the polyacetal and the polyfluorovinylidene; and a molded article formed from the above polyacetal resin composition. This resin composition has excellent resistance to frictional wear and heat stability, and is useful as a material for slide parts for use in electric and electronic appliances, business machines, automobiles, and other industrial machines.
