摘要:
The present invention relates to a portable multi-sewing machine having an interior structure simplified by defining the inside space of the sewing machine into a sewing needle part, a lever part, a motor part, a power supply part and the like so as to reduce parts, size or weight due to additional spaces provided for using an upper thread and a lower thread to the inside of the sewing machine, such that the single sewing machine can be convenient to carry around and to be used without any limitation of places, and adsorption plates (see explanation of terms) provided to the bottom surface of the sewing machine such that sewing work can be performed at any place where the sewing machine can be attached by means of the adsorption plates.

Die Erfindung betrifft ein Verfahren zum Betrieb einer Kettenstichnähmaschine und eine Kettenstichnähmaschine, die ein Nähorganpaar aus einer, in ein Nähgut (2) einstechenden Nadel (3) und einem unterhalb einer Nähgutauflage angeordneten, entlang einer Bewegungsbahn bewegbaren Greifer (11) aufweist, wobei mit der Nadel (3) ein Oberfaden (6) durch das auf der Nähgutauflage aufliegende Nähgut (2) geführt wird, der mit einem Unterfaden (7) verkettet wird. Um eine gattungsgemäße Kettenstichnähmaschine derart weiterzubilden, dass zur Ausbildung eines sauberen Nähgutmusterbildes auf der Unterseite des Nähguts die erforderliche Fadenmenge des Unterfadens verringert wird, wird mit der Erfindung vorgeschlagen, dass der Unterfaden (7) bedarfsweise einem Halteelement (27) zugeführt und in diesem gehalten wird, das hinsichtlich seiner Bewegungsrichtung und/oder Bewegungsgeschwindigkeit zur Nähgutauflage entsprechend einer Bewegungsbahn einer Schwenkbewegung des Greifers (11) insbesondere entlang einer kreisbogenabschnittförmigen Bewegungsbahn bewegt wird.

The present invention relates to an airbag cushion and an airbag system including the same, and particularly to an airbag cushion, including: at least one fabric; and seam parts connecting the fabric, wherein deviation of upper seam thread length per a unit length of the fabric between the first seam part sewed in forward direction and the second seam part sewed in reverse direction in the seam parts is 15% or less, a method of preparing the same, and an airbag system including the same. The airbag cushion of the present invention is superior in working stability and unfolding performance because of the optimized properties of the seam parts, provides superior shape stability and air-tight effect at the same time, and can protect a passenger by minimizing the shock given to the passenger.
