Problems solved by technology

Since they are permanently mounted to the door trim, they negatively affect the overall interior spaciousness
Consequently, these existing handrails can limit the possibilities in door trim design, so that interior style and volume are thus unnecessarily compromised
[0003] The presence of these armrests can also reduce the gap between the occupant and the door trim, and thus affect proper side airbag deployment and airbag volume
Also relatively stiff armrests can contact the occupant in a side impact and cause considerable rib deflection

Embodiment Construction

[0050] Referring to the drawings, like reference numerals are used to designate like components. In the following description, different operating parameters and components are described for different constructed embodiments. These specific parameters and components are included as examples and not intended to be limiting.

[0051] In one or more embodiments, the present invention is beneficial at least because the armrest may be configured to be retractable in response to adverse events such as a collision and especially a side impact. During or during such an adverse event, the armrest can be quickly retracted to increase the clearance between the occupant and the door trim for proper side airbag deployment and increased safety. This design also helps to reposition the armrest away from vulnerable areas of the occupant such as ribs and thus improves occupant performance and safety.

[0052] Another advantage of an armrest according to the present invention in one or more e...

Abstract

The present invention in one or more embodiments provides a seat assembly of a vehicle, including a seat base, a seat back communicating with the seat base, an armrest communicating with at least one of the seat back and the seat base, and a pretension unit connected to the armrest such that the armrest is retractable upon an activation of the pretension unit. The pretension unit may include a pretensioner, a pulley, and a cable.

Description

technical field [0001] The inventive concept generally relates to armrests that are retractable in adverse events, such as in the event of a crash, especially a side impact. Background technique [0002] Certain existing vehicle interiors are designed with armrests integrated with the door trim. Since they are permanently mounted to the door trim, they negatively affect the overall interior spaciousness. Consequently, these existing armrests can limit the possibilities in door trim design, so that interior style and volume are thus unnecessarily compromised. [0003] The presence of these armrests may also reduce the gap between the occupant and the door trim, and thus affect proper side airbag deployment and airbag volume. Also relatively stiff armrests can contact the occupant in a side impact and cause considerable rib flexing. [0004] It would therefore be advantageous if an armrest could be provided that addressed one or more of these identified problems. Contents...
