Abstract
A vehicle includes a passenger compartment having a roof structure having a front header, a pair of side headers and a rear header. A headliner is disposed beneath the roof structure. At least one inflatable bladder is disposed along at least one of the front header, the pair of side headers and the rear header. The at least one inflatable bladder is connected to an inflator. A rib structure is disposed adjacent to the at least one inflatable bladder. The inflatable bladder inflates to a maximum height of 12 cm below the at least one of the front header, the pair of side headers and the rear header.
Claims16
A vehicle, comprising:
- a passenger compartment having a roof structure having a header;
- a headliner disposed beneath the roof structure;
- at least one inflatable bladder having an uninflated state and an inflated state wherein in both the uninflated state and the inflated state, the at least one inflatable bladder is disposed in a covering relationship over the header and the at least one inflatable bladder being connected to an inflator;
- and
- a rib structure including a plurality of ribs in contact with the at least one inflatable bladder in both the uninflated state and the inflated state and sandwiched between the at least one inflatable bladder and the header in both the uninflated state and the inflated state.
A vehicle, comprising:

- at least one inflatable bladder having an uninflated state and an inflated state wherein in both the uninflated state and the inflated state, the at least one inflatable bladder is disposed in a covering relationship over the header and the at least one inflatable bladder being connected to an inflator;
- a rib structure in contact with the at least one inflatable bladder in both the uninflated state and the inflated state and sandwiched between the at least one inflatable bladder and the header in both the uninflated state and the inflated state, wherein the rib structure includes a plurality of ribs that have a height of between 3 and 8 mm;
- and
- wherein the at least one inflatable bladder inflates to a maximum height of 12 cm below the header.
A vehicle, comprising:
- a passenger compartment having a roof structure having a header;
- at least one inflatable bladder having an uninflated state and an inflated state wherein in both the uninflated state and the inflated state, the at least one inflatable bladder is disposed in a covering relationship over the header with a pair of opposite side edges of the at least one inflatable bladder being fixed to the roof structure and the at least one inflatable bladder being connected to an inflator;
- and
- a rib structure including a plurality of ribs in contact with the at least one inflatable bladder in both the uninflated state and the inflated state and wherein the at least one inflatable bladder is sandwiched between the plurality of ribs and the header in both the uninflated state and the inflated state, wherein the plurality of ribs have a height of between 3 and 8 mm.
