  • Patent number: 10696234
    Abstract: A covering shelf apparatus for a vehicle is provided. The apparatus is convertible into a using state in which the covering shelf operating separately from a tailgate closes a luggage compartment, a standing state in which the covering shelf is open at an angle, and a stowed state in which the covering shelf is inserted behind a rear seat. Accordingly, freight is capable of being loaded on the covering shelf in the using state in which the covering shelf closes the luggage compartment. Since the covering shelf is operated separately from the tailgate, the covering shelf is capable of being used more conveniently.

  • Patent number: 9805706
    Abstract: Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.

  • Publication number: 20130341120
    Abstract: Disclosed is a soundproof material fabricated using recycled polyurethane foam from waste seats and a process of fabricating the same, and more particularly, a soundproof material fabricated by stacking a thermoplastic polymer on a sound absorbing material including recycled polyurethane foam from seats from end-of-life vehicles and a process of fabricating the same. Use of recycled resources provides an eco-friendly impact, reduces manufacturing costs for parts, and allows for improved mechanical rigidity and sound insulating properties. The soundproof material may be applied to various automobile parts such as package trays, luggage coverings, covering shelves, and isolation pads.

  • Patent number: 7735854
    Abstract: A ramp bracket assembly for a vehicle air bag is configured to be mounted to an inner panel of the vehicle. The assembly includes a first ramp bracket with a first engagement portion, and a second ramp bracket with a second engagement portion removably engaged with the first engagement portion. The second engagement portion is disengaged from the first engagement portion in a vehicle impact, such that the assembly absorbs shock and guides deployment of the air bag. Alternatively, a ramp bracket for a vehicle air bag is configured to be mounted to an inner panel of the vehicle. The inner panel has an engagement groove, and the ramp bracket has an engagement portion, removably engaged into the engagement groove, and disengaged therefrom in a vehicle impact such that the bracket absorbs shock and guides deployment of the air bag.
