Abstract
The present disclosure provides an inflatable air cushion system of a vehicle seat. The inflatable air cushion system includes an inflatable air cushion positioned within a side supporting portion of the seat and configured to expand away from a middle supporting portion of a cushion substantially in a widthwise direction, an inflator connecting to the inflatable air cushion, and a controller for controlling the inflator to inflate the inflatable air cushion in response to a passenger occupancy signal.
Claims18
An inflatable air cushion system of a vehicle seat, comprising:
- an inflatable air cushion positioned within a side supporting portion of the seat with a length and a width configured to be fitted into the side supporting portion of the seat, wherein the inflatable air cushion includes a first portion formed of non-inflatable material and a second portion formed of inflatable material, and wherein the first portion is positioned adjacent to the middle supporting portion of the cushion and the second portion substantially expands in a widthwise direction away from the middle portion when charged;
- an inflator connecting to the inflatable air cushion;
- and
- a controller to control the inflator to inflate the inflatable air cushion in response to a passenger occupancy signal.
A seat assembly of a vehicle, comprising:
- a cushion including a middle supporting portion and two side supporting portions respectively positioned at opposing sides of the middle supporting portion;
- an inflatable air cushion positioned in at least one of the side supporting portions along a side of the side supporting portion;
- a guiding member in the side supporting portion and formed of rigid material;
- an inflator connecting to the inflatable air cushion;
- and
- a controller configured to control the inflator to inflate the inflatable air cushion when it is determined that there is a passenger on the cushion such that the inflatable air cushion expands substantially in a widthwise direction away from the middle supporting portion of the cushion,
- wherein the side supporting portion of the cushion includes a cover layer surrounding the inflatable air cushion and the guide member, and the inflatable air cushion is positioned between the guide member and a side portion of the cover layer, and
- wherein the guiding member obstructs expansion of the inflatable air cushion toward the middle supporting portion such that the inflatable air cushion substantially expands away from the middle supporting portion.
A method of adjusting a vehicle seat assembly, the vehicle including a console unit, the seat assembly including a cushion, an inflatable air cushion positioned in the cushion along a side of the cushion adjacent to the console unit, a guiding member in the cushion, and an inflator connected to the inflatable air cushion, the method comprising:
- determining if there is a passenger on the seat;
- and
- controlling the inflator to inflate the inflatable air cushion in response to a passenger occupancy signal such that the inflatable air cushion expands away from the guide member toward the console unit to reduce a gap between the side of the cushion and the console unit,
- wherein the guide member is formed of rigid material and the air inflatable air cushion is positioned between the guide member and the side of the cushion adjacent to the console unit.
