Abstract
A three-dimensional air bag includes a first three-dimensional sewn portion, a second three-dimensional sewn portion and a flat sewn portion as defined herein, a shape of the first three-dimensional sewn portion in the main panel in a flat state is different from a shape of the first three-dimensional sewn portion in the first side panel in a flat state, a shape of the second three-dimensional sewn portion in the main panel in the flat state is different from a shape of the second three-dimensional sewn portion in the second side panel in a flat state, and a shape of the flat sewn portion in the first side panel in the flat state and a shape of the flat sewn portion in the second side panel in the flat state are the same.
Claims3
A three-dimensional air bag in which a main panel, a first side panel, and a second side panel are sewn together, the air bag comprising:
- a first three-dimensional sewn portion in which the main panel and the first side panel are sewn together, a second three-dimensional sewn portion in which the main panel and the second side panel are sewn together, and a flat sewn portion in which the first side panel and the second side panel are sewn together, wherein
- at least a part of the flat sewn portion is at a lower surface of the air bag when the air bag is deployed and inflated,
- at least a part of the first three-dimensional sewn portion and at least a part of the second three-dimensional sewn portion are at an upper surface of the air bag when the air bag is deployed and inflated,
- a shape of the first three-dimensional sewn portion in the main panel in a flat state is different from a shape of the first three-dimensional sewn portion in the first side panel in a flat state,
- a shape of the second three-dimensional sewn portion in the main panel in the flat state is different from a shape of the second three-dimensional sewn portion in the second side panel in a flat state,
- a shape of the flat sewn portion in the first side panel in the flat state and a shape of the flat sewn portion in the second side panel in the flat state are the same, and
- the three-dimensional air bag further comprises
- an overlapped sewn portion in which a part of the main panel, a part of the first side panel, and a part of the second side panel are overlapped and sewn together, wherein
- at least a part of the overlapped sewn portion is at a front surface of the air bag when the air bag is deployed and inflated, and
- a shape of the overlapped sewn portion in the main panel in the flat state, a shape of the overlapped sewn portion in the first side panel in the flat state, and a shape of the overlapped sewn portion in the second side panel in the flat state are the same.
