Description

TECHNICAL FIELD

The present disclosure relates to the field of a safety arrangement for a vehicle. More particularly, the present disclosure relates to a safety arrangement for proper deployment of an airbag arranged on a vehicle seat placed adjacent/beside a console box.

BACKGROUND

Airbags mostly comes as a standard equipment inside the vehicle. The airbag is a safety device which operates in an emergency such as a vehicle collision/vehicle impact and protects an occupant by deploying the airbag cushion (with a fluid/gas pressure in the airbag) towards the occupant and prevent any injury causing the occupant.

Air bags are installed in various positions. For example, a front airbag is provided at a centre of a steering wheel so that a driver can be protected from a collision occurred from the forward and backward directions. In addition, in order to protect an occupant from an impact in a vehicle width direction by such as a side collision, a side airbag is provided at a side part of a seat arranged adjacent/beside a console box to protect the occupants. During a collision or on an impact in a lateral/transverse direction of the vehicle, the side airbag deploys between the vehicle seat and the (centre) console box.

When the airbag is deployed in case of a vehicle impact, the lid may restrict the proper deployment of the airbag if the lid overlaps with the deployment path of the air bag which is understandably not desirable.

Therefore, there is a need to overcome the above drawback(s) and provide a safety arrangement for the vehicle.

The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details.

The present disclosure relates to a safety arrangement for a vehicle interior which allows a side airbag of a vehicle seat to deploy in case of an impact without getting hindered by a lid of a console box arranged adjacent/beside of the seat.

Referring now to FIG. 1, a safety arrangement (100) for a vehicle interior in accordance with the present invention is illustrated. The safety arrangement (100) includes one or more seat (200) with an airbag (300) configured to be deployed in vehicle interior in case of an impact and a console box (110) with a lid (130) arranged adjacent/beside to the one or more seat (200). The air bag (300) is arranged on a side part of the one or more seat (200) specially beside the console box (110). Particularly, the airbag (300) is deployed in a transverse and/or longitudinal direction of the vehicle interior.

The console box (110) is having a storage compartment (120) for storing articles and the lid (130) for closing an opening of the storage compartment (120). The lid (130) is coupled to the console box (110), specifically hingeably or pivotally coupled to the console box (110). The lid (130) is moveable between a fully open position (100a) and a close position (100b) as shown in FIGS. 8 and 9. The fully open position (100a) allows access to the storage compartment (120) and an occupant can dispose or place an article within the storage compartment (120) when the lid (130) is in the fully open position (100a). In the close position (100b), the lid (130) closes the opening of the storage compartment (120). The lid (130) is adapted to latch with the console box (110) in the closed position (100b), preferably by a hook-slot system. In an embodiment, a knob is arranged on/in the console box (110) or lid (130) for latching/unlatching the lid (130) with/from the console box (110). In an embodiment, the lid (130) is an armrest of the console box (110).

Referring to FIGS. 2 and 3, the lid (130) is coupled to the console box (110) by a hinge assembly (150). The hinge assembly (150) facilitates the lid (130) to move between the fully open position (100a) and the closed position (100b). The hinge assembly (150) biases the lid (130) in a first position (100c) to prevent the lid (130) from overlapping a deployment path of the airbag (300).

More particularly in an embodiment (as shown in FIG. 7), the first position (100c) is the close position (100b) (itself) where the lid (130) is latched with the console box (110). In yet another embodiment, the first position (100c) is the close position (100b) where the lid (130) is unlatched with the console box (110). In yet another embodiment (as shown in FIG. 8), the first position (100c) is an intermediate position between the fully open position (100a) and the close position (100b). Specifically, the first position (100c) is the intermediate position (100c) that is a partial open position with less than 15 degrees of an opening angle (θ) of the lid (130) with respect to the close position (100b) of the lid (130).

The lid (130) includes a first hinge plate (140) and a second hinge plate (142) as shown in FIGS. 2, 3, 4, 5 and 6. The lid (130) is moveably connected to the console box (110). Specifically, the first hinge plate (140) of the lid (130) is moveably connected to the console box (110). The second hinge plate (142) is a fixed hinge plate which is attached to a portion of a body of the console box (110). The first hinge plate (140) covers the storage compartment (120) of the console box (110). The first hinge plate (140) is covered by a cushion which provides a cushioning effect such that an upper portion of the lid (130) can be used as an armrest for the occupant.

The first hinge plate (140) and the second hinge plate (142) are connected by a shaft (145). The hinge assembly (150) is arranged between the first hinge plate (140) and the second hinge plate (142) specifically on the shaft (145). The shaft (145) is connected across a portion of the console box (110). In the present embodiment, a stopper (not shown) is arranged on each end of the shaft (145) to secure the hinge plates across the shaft (145).

In the present embodiment, the hinge assembly (150) includes a first biasing member (160) and a second biasing member (170) as shown in FIGS. 2, 3, 4 and 5. The first biasing member (160) is adapted for biasing the lid (130) in a direction towards the closed position (100b) and the second biasing member (170) is adapted for biasing the lid (130) in a direction towards the fully opening position (100a). The first biasing member (160) and the second biasing member (170) are arranged around the shaft (145) connected across a portion of the console box (110). The relationship between biasing forces of the first biasing member (160) and the second biasing members (170) biases the lid (130) to the first position (100c) to prevent overlapping of the lid (130) with the deployment path of the airbag (300) when the air bag (300) is inflated from the side portion of the seat (200).

Specifically, the lid (130) has a natural tendency to move towards the first position (100c). The lid (130) must be moved upward manually by the occupant.

The first biasing member (160) and the second biasing members (170) are coil spring. In the present embodiment, the stiffness of the second biasing member (170) is less than the stiffness of the first biasing member (160). Preferably by adjusting the characterized feature(s) of the springs like any one or combination of diameter, length, number of coil, material of the spring etc. By way of non limiting example, the change in ratio of the diameters between the first and the second biasing member is almost 20%. It may be obvious to a person skilled in the art to increase or decrease the stiffness of the biasing members to increase the effectiveness of the hinge assembly (150). The second biasing member (170) has gravity assistance and the first biasing member (160) act against the gravity. The coil helix of both the biasing members (160, 170) are opposite to each other.

Further, in the closing direction, the lid (130) moves slowly so that the closing of the lid (130) does not cause any injury to the occupant if his/her hand or finger gets trapped in between storage compartment (120) and the lid (130).

In implementation, when the occupant desire to store some articles in the console box (110) he/she have to move the lid from the close position to the open position manually like by hand. However, upon releasing his/her hand from the lid (130) the lid (130) moves to the first position (100c) due to the hinge assembly (150). The first biasing member (160) provide force for closing the lid (130) from maximum open position (˜95°) towards the closed (0°) position. The second biasing member (170) absorb the force generated by the first biasing member (160) and reduce the speed of the lid (130) while closing the lid (130) from (60° to 0°) and thus provide damping effect.

One end (160a) of the first biasing member (160) is connected to the first hinge plate (140) and other end (160b) of the first biasing member (160) is adapted to connect with the second hinge plate (142). The first biasing member (160) is designed in such way that the second end (160b) of the first biasing member (160) contacts with the second hinge plate/fixed plate (142) only after opening the lid (130) for angle of 70° as shown in FIG. 5. Similarly, one end (170a) of the second biasing member (170) is connected to the first hinge plate (140) and other end (170b) of the second biasing member (170) is adapted to connect with the second hinge plate (142). The resting ends of the first biasing member (160) and the second biasing member (170) are covered with TPE (NVH) material to avoid noise coming from movement with fixed second plate.

Therefore, the advantage of the present invention is to provide a safety arrangement inside a vehicle interior which allows a side airbag deployment without getting hindered by a lid of the centre console. The arrangement prevents injury to an occupant if his/her hand or finger gets trapped in between floor console and the lid. The safety arrangement is simple and is robust in construction.
