Abstract: A functional unit adjusts a seat back of a vehicle seat and contains a functional support with an electrical pinion adjuster arranged thereon for moving the seat back, a blocking mechanism for blocking the backrest movement, and a seat adapter unit for securing to a seat substructure. The functional support has an upright bearing pin which forms a backrest rotational axis for the backrest movement together with the seat adapter unit. The blocking mechanism has a pawl system and a fixed blocking element. The pawl system is rotatably mounted on the functional support and has two blocking positions for blocking the backrest movement at opposing end sides of the blocking element. A rotatably mounted tooth segment is arranged on the bearing pin, which has a segment toothing engaged with the pinion adjuster and a protrusion. The blocking element has a recess for the tooth segment with two end-side stops.

Abstract: It is provided a vehicle seat having a longitudinal adjustment assembly for adjusting the vehicle seat along a longitudinal axis, wherein the longitudinal adjustment assembly comprises a locking device for locking the vehicle seat in a seat longitudinal position along the longitudinal axis, a pivotable actuation element having an actuation portion and a coupling portion, wherein an adjustment force for actuating the locking device can be introduced into the actuation element via the actuation portion and the coupling portion is provided for transmitting the adjustment force to the locking device, and a supporting element for supporting the actuation element during a pivoting movement of the actuation element, which pivoting movement is to be carried out for the transmission of the adjustment force to the locking device. The supporting element is formed by a separate component mounted on a structural element of the vehicle seat.

Abstract: To manufacture spherical particles out of liquid phase with a narrow grain spectrum using melting temperatures of up to 1500.degree. C. by generating droplets by means of vibrating nozzles, the liquid phase, the nozzle and the drop distance for the droplets are maintained at a constant temperature of 1.degree. to 10.degree. C. above the melting temperature of the liquid phase until the spherical shape of the falling droplets has stabilized. The particles must then be abruptly chilled.
