Patent number: 5034570Abstract: A vehicle seat disposed in a vehicle is movable longitudinally in the vehicle. A guide device guides a line, e.g. an electrical or a pneumatic line, between a fixed position in the vehicle and the movable seat and guides it as the seat shifts longitudinally. The line is formed of relatively rigid material with elastic properties which is bendable, e.g. from a stiff, elastic covering over the line. The guide device includes two spaced apart, horizontal, support pieces extending in the longitudinal direction. The line is bent into a U and the legs of the U bear against respective support pieces. The length of the line is such that the line retains its U-shape as the seat shifts longitudinally. The support pieces have respective side walls which define an opening between them through which the line projects to the seat. The front part of the line that is attached to the seat is bent off the support piece at an angle.Type: GrantFiled: June 21, 1989Date of Patent: July 23, 1991Assignee: Saab-Scania AktiebolagInventor: Rolf Johansson

Patent number: 5029929Abstract: A vehicle seat (8) comprises a backrest (7) which consists of an upper and a lower backrest part (14,15). The lower backrest part (15) is connected in an articulated manner both to a seat part (9) and to the upper backrest part (14). By swinging the lower backrest part (15) forwards in the longitudinal direction of the vehicle and the upper backrest part (14) backwards in the longitudinal direction, the vehicle seat (8) is converted into part of a bed.Type: GrantFiled: February 14, 1990Date of Patent: July 9, 1991Assignee: Saab-Scania AktiebolagInventors: Staffan Sjostrom, Rolf Johansson

Patent number: 4887191Abstract: The invention relates to an arrangement for the suspension of a headlamp (5) on the front (4) of a driver's cab (1) which is spring-mounted on a chassis frame (2). The object of the invention is to prevent relative movements between the driver's cab (1) and the chassis frame (2) from affecting the alignment of the optic axis of the headlamp (5). The invention is essentially characterized in that each headlamp (5) is pivotably connected to an upper and lower connecting arm respectively (29, 40), which connecting arms are pivotably connected to the chassis frame (2), and in that one connecting arm (29) is also pivotably connected to the driver's cab (1).Type: GrantFiled: October 7, 1988Date of Patent: December 12, 1989Assignee: Saab-Scania AktiebolagInventor: Rolf Johansson

Patent number: 4854447Abstract: A belt conveyor with dual upper runs and dual lower runs defined by a single continuous belt for synchronized movement of the upper runs. The dual lower runs cross each other and are guided by longitudinally spaced support rollers which twist the lower belt runs and vertically shift at least one of these lower runs to provide for free unencumbered crossing of the lower belt runs and the keepers mounted on the belt to assist in movement of material.Type: GrantFiled: April 18, 1988Date of Patent: August 8, 1989Inventor: Rolf Johansson

Patent number: 4738353Abstract: In belt conveyors having two parallel belts (1) with feeders, movement of the belts must be synchronized. The known method of achieving this is by means of electrical systems. The present invention entails a radical simplification of this synchronization by using a single belt (1) crossing over below the conveyor, the two parallel sections on the upper side of the conveyor thus moving snychronously. The conveyor according to the invention is less expensive and more reliable than previously known conveyors, nor is it dependent on a source of electric power.Type: GrantFiled: October 14, 1986Date of Patent: April 19, 1988Inventor: Rolf Johansson

Patent number: 4716272Abstract: A method of attaching a connection piece of metal to a metal surface by brazing wherein the required heat is generated by an electric arc. The heat generated by the electric arc is conducted through at least a portion of the connection piece and melts a brazing metal provided between the connection piece and the metal surface. The heat conducting portion of the connection piece prevents direct contact between the electric arc, the metal surface and the brazing metal during melting which prevents disadvantageous thermal actuation of the metal surface. When the current to the electric arc has been disconnected, a mechanical force is applied to the heat conducting portion of the connection piece pressing the latter against the metal surface and pressing out a portion of the brazing metal from underneath the remaining joint-forming surfaces of the connection piece.Type: GrantFiled: July 19, 1985Date of Patent: December 29, 1987Assignee: AGA AktiebolagInventors: Per A. Blad, Rolf Johansson

Patent number: 4366900Abstract: When building, particularly private houses, it is necessary to convey goods such as roof tiles up to the roof. Conveyors have been produced which are of fixed shape, heavy and inconvenient to transport. The present invention presents a conveyor which is light and takes up little space when being transported. The conveyor consists of a central unit (I) comprising a telescopic tube which can be collapsed during transportation and pulled out to its full length for operation. The central unit is provided at each end with two transverse units (3L, 1A) over which two parallel belts (1E) are placed, said belts being preferably of nylon and being provided with a number of pushers (3H) arranged one after the other. A synchronization means (3A-D FIG. 2) is provided to align the pushers on the two belts at the same transverse level.Type: GrantFiled: December 20, 1980Date of Patent: January 4, 1983Inventor: Rolf Johansson
