Description

The present invention relates to a motor vehicle with a pedal console and a seat.

State of the art

Depending on the type of vehicle used and the distinction between driver and passenger seats and the level of equipment, a wide variety of seats for the occupants of motor vehicles have been proposed. The driver's seat is usually on the side facing oncoming traffic; opposite him are the steering and control instruments. Depending on the equipment level, car front seats are more or less padded or have ergonomic shapes and headrests. At higher levels of equipment and especially in sports cars, the backrests are sometimes bulged laterally in order to absorb the lateral centrifugal forces acting on the upper body during cornering in favor of improved lateral support.

The extent and differentiation of the seat adjustment largely depends on the level of comfort and equipment and ranges from so-called linear or two-way to four-way and six-way systems based on the state of the art. With electrical adjustment, several different seat settings can be stored electronically and activated for changing ("memory function"). Especially for frequent and professional drivers, the seats protect the human musculoskeletal system from one-sided and thus unhealthy strains and unhealthy sitting positions.

Out EP 2 965 955 A1 is known per se to attach a seat frame to an external frame. The outer frame is connected to a rocking frame mounted on a pair of rails on the vehicle floor.

In DE 21 57 899 C3 it is proposed to encircle and support the backrest of the seat with a reinforcement bracket which is hinged to the vehicle floor. The seat belts are also attached to the reinforcement bar.

Another outer reinforcement frame for the seat back is in DE 601 15 381 T2 described, with the reinforcement frame being connected here to the B-pillar of the vehicle. JP 2012-086682 A reveals a similar concept.

EP 1 987 982 A1 , DE 26 44 412 A1 such as U.S. 6,340,208 B1 each describe a seat for a motor vehicle, which comprises a backrest and a connecting element for rigidly connecting to the motor vehicle. The respective seat is pivotally mounted on the backrest with respect to the connecting element.

In DE 11 2009 000 495 B4 discloses an responsive seat cushion adapted for use with a seat defining an outer surface. In a preferred embodiment, the cushion comprises a structure which is housed in the seat and is spaced a first distance in a first position spaced from the surface. An actuator is drivingly coupled to the structure and includes an active material element. A signal source is operable to generate and provide an activation signal to the element to power the pad. The actuator is configured to move the structure to a second position spaced from the surface a second distance different from the first when the material element is activated. More preferably, the actuator is configured to move the structure to one of multiple possible second positions, for example through the use of multiple active material elements or a locking mechanism having multiple stops.

EP 2 998 222 B1 relates to a driver's seat with a seat bottom and a backrest, which form a support structure and a bearing surface for a seat occupant, wherein a reference point of the seat is determined, which is located in an axial vertical plane of the seat at a junction of bearing surfaces of the seat bottom and the backrest which seat the backrest is articulated on the seat bottom about a tilting axis of the backrest erected in a direction of an axis perpendicular to the total axial symmetry vertical plane located in a lower part of the backrest and in a rear part of the seat bottom by a tilting angle of the backrest with respect to an adjustable vertical direction, the backrest comprising a backrest lower panel held on the side of a lower edge of the backrest lower panel with a rear edge of the seat bottom to form the variable inclination angle of the backrest den, and an upper back panel located in extension and above the lower back panel, an angle of elevation of the upper back panel relative to the lower back panel is variable when the seat is in use, the seat bottom comprises a rear seat bottom panel with a constant fixed inclination in Relating to a substantially horizontal support structure of the seat and comprising a front seat panel extending in extension and forward of the rear seat panels panel is located, the angle of inclination of the seat bottom of the front seat-bottom panel with respect to the rear seat-bottom panel is variable when the seat is occupied, and the seat includes a work position in which the seat occupant is in a seated position with the backrest upright and the seat bottom horizontal, and an alert position, in which the seat occupant occupies the seat while the backrest is reclined and raised in an upper part corresponding to the upper backrest panel and the seat bottom is raised in a front part corresponding to the front seat bottom panel.

A seat according to US 2015/0008707 A 1 includes a seat pan having a front seat pan edge and a rear seat pan edge. The front edge of the seat pan defines a first pivot point and the rear edge of the seat pan defines a second pivot point. A lumbar pad having a lumbar pad top edge and a lumbar pad bottom edge is hingedly disposed adjacent the rear edge of the seat pan. A backrest having a backrest top edge and a backrest bottom edge is articulated adjacent the lumbar cushion top edge. A headrest with a headrest upper edge and a headrest lower edge is arranged in an articulated manner next to the backrest upper edge. The seat shell, lumbar cushion, backrest and headrest can be positioned in relation to each other so that the seat can be configured in a maneuvering, take-off, landing, limited reclining, snoozing or sleeping position. The first pivot remains stationary for each of the positions.

DE 10 2015 204 492 A1 finally discusses a massage device for a vehicle seat with a massage element that moves a contact surface of the vehicle seat by means of an electromechanical actuator to massage the person sitting on the vehicle seat and has a spring element whose shape in relation to the contact surface of the vehicle seat is controlled by a device containing the electromechanical actuator Restoring element is changeable.

Embodiments of the invention

the 1 until 3 illustrate in their synopsis the ergonomic functioning of a seat according to the invention (10, 17, 18, 20), by simply pivoting the
Seat upholstery (26) in the direction of travel optionally an optimal steering position for the vehicle occupants (11 - 1 ), working position (12 - 2 ) or relaxation position (13 - 3 ) can take. Body positions of all body sizes and postures of possible vehicle occupants are referenced in the shoulder area (14), also with regard to extended acoustic requirements, as in the shoulder position (14) corresponding positions according to 4 , 5 and 6 illustrate.

Like before everything 7 shows that the seat (10, 16-20) is pivotably mounted on the backrest (10) for this purpose and - in this case by means of a frame (16) which connects the seat frame (27) and pedal console (21) to form a common module - on the shell connected. The height is adjusted by adjusting the padding on the buttocks (17) and thighs (18) in the Z direction of the vehicle coordinate system, while comfort is adjusted by tilting the padding on the buttocks (17), thighs (18), lordosis (19) and head (20). The cushions for the buttocks (17), thighs (18) and lordosis (19), which can also be adjusted longitudinally, a foot console that can be adjusted in the X direction of the vehicle coordinate system and a steering wheel (24) that can be adjusted in the same direction, finally allow adjustment to the size of the vehicle occupant.

the 8th until 13 illustrate using two vehicle models in steering position (11), working position (12) and relaxation position (13) the variable use of space, which is made possible by the features of the seating system according to the invention. When transitioning from the steering position (11 - 8th or. 11 ) into the working (12 - 9 or. 12 ) or relaxation position (13 - 10 or. 13 ) the pedals (22) are moved with the console and folded in around the Y-axis, while the steering module (25) pivots and retracts. The feet (23) of the vehicle occupant can thus be relaxed on the console.

The advantages of these properties in the overall system can be for the steering position (11), working position (12) and relaxation position (13). 14 , 15 or. 16 remove. These drawings make it clear how the seat system can be swiveled forwards and upwards without the lying vehicle occupant “diving” under the beltline. This does not result in any significant restriction of space in the rear; rather, up to four units according to the invention can be integrated in an upscale equipment package.

At the same time, the approach described preserves the greatest possible constancy of the gripping spaces for visual functions and other features with minimal position variance of head, shoulders (14) and back and creates an optimized area for the design of acoustic properties of the vehicle (15). Massage elements can also be ideally positioned for any body size.

Other properties of the seat (10, 16-20, 30) are now based on the 17 explained. In particular, the stepless adjustment possibility of the seat cushions (26) forming the seat for the head, back, lordosis, pelvis and thighs with a high degree of freedom opens up a wide range of fixation, stabilization and comfort seat positions, which also allow adjustment to or for all body sizes. allow compensation for any postural damage.

The decoupling of the seat elements, which can be positioned relative to the backrest (10) via a seat frame (27), from the restraint systems also offers advantages. In this way, the seat frame (27) ensures stabilization of the vehicle occupants, while the frame (16) secures them according to the operating principle of an exoskeleton and the backrest guarantees a stationary connection to the vehicle structure. It is also possible to secure the pelvic area of the vehicle occupant in the event of an unexpected collision; other restraint systems like direct or over the frame (16) be connected to the shell. The concept according to the invention thus allows new load paths to be formed in the overall structure of the vehicle (15).

The remaining 18 until 20 and 21 until 23 illustrate the properties of the pedal console steering module system (29) in the steering position (11 - 18 or. 21 ), working position (12 - 19 or. 22 ) and relaxation position (13 - 20 or. 23 ). The stepless movement or retraction of the steering module (25) forwards and downwards improves the ergonomics of the gripping and viewing areas, while the free space for getting in and out, which is maximized according to the invention, increases the comfort of the vehicle occupants.

The continuous process of the pedal console (21) - associated with a retraction of the pedals (22) from their in the 18 and 21 extended position - improves ergonomics with regard to different leg lengths and use cases. In addition, the pedal console (21), which can thus be used to support the legs, proves to be extremely flexible, for example in comparison to calf pads firmly integrated with the seat (10, 16-20, 30).

Finally, the properties of the pedal console steering module system (29) described in their entirety open up numerous constructive possibilities for coordinating the access times with conditional, high or full automation in accordance with SAE J3016.
