Safety seat and method for reducing stress on an occupant of a motor vehicle
First Claim
1. A method of reducing the impact of a force upon a person seated in a safety seat of a motor vehicle, comprising:
- restraining at least a seat unit of the safety seat at least in part by at least one support strap;
forming the at least one support strap with an extension piece configured to lengthen when exposed to a load as a result of an accident or explosion;
holding the at least one support strap in a winding unit to shorten an effective length of the at least one support strap and to build up a force to maintain the at least one support strap under tension after the support strap underwent a lengthening in an area of the extension piece as a result of a load caused by a force resulting from an accident or explosion so as to reestablish an effective length of the support strap for lengthening during a subsequent force impact;
connecting an upper part of a back unit to a structure of a motor vehicle and configuring a lower part of the back unit to allow a lowering thereof in relation to the upper part of the back unit;
articulating a forward part of the seat unit to the upper part of the back unit and articulating a rear part of the seat unit to the lower part of the back unit and configuring the rear part to drop father than the forward part of the seat unit when a force resulting from an accident or explosion acts on the motor vehicle.

Abstract
In a method for reducing the impact of a force upon a person seated in a safety seat of a motor vehicle at least a seat unit of the safety seat is restrained at least in part by at least one support strap. The support strap is formed with an extension piece configured to lengthen when exposed to a load as a result of an accident or explosion. A winding unit holds the support strap to shorten an effective length of the support strap and to build up a force to maintain the support strap under tension after the support strap underwent a lengthening in an area of the extension piece as a result of a load caused by a force resulting from an accident or explosion so as to reestablish an effective length of the support strap for lengthening during a subsequent force impact.

6. A safety seat for a motor vehicle, comprising:
-
a seat unit; at least one first support strap restraining the at least one seat unit at least in part, said first support strap having an extension piece configured to lengthen when exposed to a load as a result of an accident or explosion; and a winding unit holding the first support strap, said winding unit configured to shorten an effective length of the first support strap and to maintain the first support strap under tension in the event the first support strap underwent a lengthening as a result of a load caused by a force resulting from an accident or explosion so as to reestablish the extension piece within the effective length of the support strap for lengthening during a subsequent force impact; and a back unit having an upper part for connection to a structure of a motor vehicle, and a lower part configured to allow a lowering thereof in relation to the upper part of the back unit, wherein the seat unit has a forward part which is articulated to the upper part of the back unit, and a rear part which is articulated to the lower part of the back unit and is configured to drop father than the forward part of the seat unit when a force resulting from an accident or explosion acts on the motor vehicle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
